2018 stands as a landmark year in the history of Tamil cinema, often referred to as Kollywood. It was a year characterized by extreme contrasts: high-budget sci-fi spectacles that pushed technical boundaries, intense political dramas reflecting the state's socio-political climate, and intimate, soul-stirring romances that captured the public imagination.
From the massive global footprint of Rajinikanth's 2.0 to the sleeper success of the nostalgic '96, 2018 demonstrated that the Tamil film industry was maturing both in terms of commercial viability and narrative depth. Here is a comprehensive look at the highest-grossing Tamil films of 2018 and the factors that led to their monumental success.
1. 2.0 – The Sci-Fi Goliath
Worldwide Gross: Approx. ₹700 – ₹800 Crore
Director: S. Shankar
Starring: Rajinikanth, Akshay Kumar, Amy Jackson
2.0 was not just a movie; it was a cultural event. As the spiritual successor to the 2010 blockbuster Enthiran, the film carried immense expectations. Directed by the visionary S. Shankar, it remains one of the most expensive Indian films ever made, with a budget estimated between ₹500 and ₹600 crore.
Box Office Performance
The film’s performance was nothing short of historic. It shattered records across the globe, becoming the highest-grossing Tamil film of all time (a record it held for years). Its success was bolstered by a massive release in Northern India, where the presence of Bollywood superstar Akshay Kumar as the antagonist, Pakshi Rajan, helped it rake in over ₹200 crore from the Hindi version alone.
Why It Succeeded
* Visual Spectacle: The film was shot entirely in 3D, a rarity in Indian cinema. The VFX, handled by international studios, set a new benchmark for what was possible in regional filmmaking.
* The Rajini Factor: Despite being in the industry for over four decades, Rajinikanth’s "Superstar" pull remained the primary engine behind the film's massive opening.
* Social Message: Shankar stayed true to his brand by weaving a strong environmental message—the impact of mobile phone radiation on birds—into a high-octane superhero narrative.
2. Sarkar – The Political Firebrand
Worldwide Gross: Approx. ₹250 – ₹260 Crore
Director: A.R. Murugadoss
Starring: Vijay, Keerthy Suresh, Varalaxmi Sarathkumar
If 2.0 was about technology, Sarkar was about the pulse of the people. Released during the Diwali season, Sarkar saw "Thalapathy" Vijay team up with director A.R. Murugadoss for the third time (after Thuppakki and Kaththi).
Box Office Performance
The film took one of the biggest openings in Tamil cinema history. In Tamil Nadu, it briefly outperformed 2.0 in certain territories during its initial run. Despite facing significant political controversy—including protests from the ruling party over certain scenes—the film maintained strong momentum, eventually crossing the ₹250 crore mark worldwide.
Why It Succeeded
* Timely Theme: The film focused on "Section 49P" of the Election Rules and the issue of fraudulent voting. Given the political climate in Tamil Nadu at the time, the theme resonated deeply with the youth.
* Vijay’s Screen Presence: Vijay’s portrayal of a high-flying CEO turned political activist was a massive hit with his core fan base.
* Controversy Boost: As is often the case in Kollywood, the political opposition the film faced served as free marketing, driving curious audiences to the theaters in droves.
3. Kaala – The Subversive Revolutionary
Worldwide Gross: Approx. ₹155 – ₹160 Crore
Director: Pa. Ranjith
Starring: Rajinikanth, Nana Patekar, Huma Qureshi
2018 was a rare year where Rajinikanth had two major releases. While 2.0 was a mainstream entertainer, Kaala was a gritty, symbolic exploration of land rights and caste politics set in the slums of Dharavi, Mumbai.
Box Office Performance
While Kaala didn't reach the astronomical heights of 2.0, it was a solid commercial success. It grossed over ₹150 crore, though it faced stiff competition and some resistance in certain markets due to its heavy political undertones.
Why It Succeeded
* Artistic Depth: Pa. Ranjith used Rajinikanth’s stardom to deliver a profound message about the struggle of the oppressed. The climax, utilizing colors (black and red vs. white), became a talking point in Indian cinema.
* The Antagonist: The face-off between Rajinikanth’s Karikaalan and Nana Patekar’s Hari Abhayankar provided some of the most intense dialogue-driven scenes of the year.
4. Vada Chennai – The Gangster Epic
Worldwide Gross: Approx. ₹75 – ₹90 Crore
Director: Vetrimaaran
Starring: Dhanush, Ameer, Andrea Jeremiah, Aishwarya Rajesh
Vetrimaaran’s Vada Chennai is widely considered one of the greatest gangster films in Indian history. A non-linear narrative spanning decades, it told the story of a skilled carrom player who gets pulled into the murky world of North Chennai's gang wars.
Box Office Performance
Despite its "A" rating (restricting the audience to adults), the film was a massive hit. It earned high praise from critics and performed exceptionally well in urban centers and overseas, proving that "raw and rustic" content had a huge market.
Why It Succeeded
* World Building: Vetrimaaran’s attention to detail in recreating the history of North Chennai was immersive.
* Performances: Dhanush delivered one of his career-best performances, supported by an ensemble cast that felt authentic to the setting.
5. Chekka Chivantha Vaanam – The Multi-Starrer
Worldwide Gross: Approx. ₹80 – ₹95 Crore
Director: Mani Ratnam
Starring: Vijay Sethupathi, Silambarasan, Arvind Swamy, Arun Vijay
Mani Ratnam returned to the gangster genre with a star-studded cast in Chekka Chivantha Vaanam (CCV). The film centered on a power struggle between three brothers after the death of their crime-lord father.
Box Office Performance
CCV was a major comeback for Mani Ratnam at the box office. The presence of four major male leads ensured a massive opening, and the slick production helped it cross the ₹80 crore mark comfortably.
6. Honorable Mentions: The "Small" Giants
While the films above led the charts in terms of raw revenue, 2018 was also the year of the "Medium Budget Blockbuster."
* '96: Starring Vijay Sethupathi and Trisha, this romantic drama grossed approximately ₹50 crore on a modest budget of ₹18 crore. It became a cult classic, staying in theaters for over 100 days.
* Kadaikutty Singam: Starring Karthi and produced by Suriya, this rural family drama grossed over ₹70 crore, proving that the "B and C" center audiences (rural and semi-urban) were still a powerhouse for the industry.
* Irumbu Thirai: This techno-thriller starring Vishal and Arjun Sarja tackled the relevant issue of cybercrime and grossed over ₹60 crore, becoming one of the biggest hits in Vishal’s career.
Summary Table of 2018's Top Grossers
Conclusion
The Tamil film industry in 2018 was a vibrant ecosystem. It successfully balanced the "Superstar" culture with a growing demand for content-driven cinema. The year proved that while the "Big Three" (Rajinikanth, Vijay, Ajith—though Ajith had no release in 2018) still commanded the highest numbers, there was ample room for directors like Vetrimaaran and C. Prem Kumar to achieve commercial success through storytelling.
As the industry moved into 2019, the lessons of 2018—that high production value must be met with engaging scripts—remained the blueprint for Kollywood’s continued global expansion.
