In 2005, he starred in Hari's "Ayya", alongside newcomer Nayanthara. The film was released on the Pongal weekend to positive reviews and was a super hit at the box office. Sarathkumar's performance fetched very positive reviews with a reviewer citing: "another splendid performance from Sarathkumar". He appeared in guest appearances in the Telugu film "Bunny" and his wife's production "Githan". The success of A. Venkatesh's "Aai" resulted in the film's team collaborating to make a film in a similar genre, "Chanakya", which also featured Namitha and Vadivelu. The film was a hit at the box office, and marked the A. Venkatesh and Sarathkumar combination's third hit in a row. He signed up for "Khaki" and shooting was in progress. Sarathkumar even tonsured his head for the film, but the film was dropped for some reason. In 2006, he directed and acted in his 100th film "Thalaimagan", produced by his wife Raadhika under the "Radaan Media works" banner. The film failed at the box office. The next year, he starred in Gautham Menon's "Pachaikili Muthucharam", which released to positive reviews, but ended up as an average grosser. A critic stated his performance: "as a next-door-family-man, Sarathkumar has excelled". Sarathkumar signed up for a Malayalam film, "Vaitheeswaran", "1977" and a film directed by K. S. Ravikumar. He then played a cameo appearance as himself in Cheran's "Maya Kannadi". Sarathkumar's last 2007 release was "Nam Naadu", a remake of the Malayalam hit "Lion", marking his third collaboration with director Suresh. This was his first film after he launched his own political party in Tamil Nadu. The film, released to largely negative reviews, failed at the box office. In 2008, his only release was the supernatural film "Vaitheeswaran", which was released to negative reviews.
