The film has Gopika playing the female lead. Gopika had earlier paired with Mammootty in the blockbuster Mayavi. Lakshmi Rai is also doing an important role in the film.
Annan Thampi is scripted by P. Nayarambalam, who has earlier given us entertaining fares like Chanthupottu and Thommanum Makkalum (which, incidentally, was also about two brothers). Shooting for the film is going at a rapid pace in Pollachi and it is expected to release this Vishu.
