Southern actor Siddharth, currently busy filming for upcoming Tamil comedy "Theeya Velai Seiyyanum Kumaru", is taken aback by the pace at which the film is shaping up.

The film, which went on the floors last month, is being directed by Sundar C, starring Siddharth, Hansika and Ganesh Venkatraman, with Santhanam as the comedian. It has music by Sathya of Engeyum Eppothum fame, which is being produced by Avni Cine Max.

" 'Theeya Velai Seiyyanum Kumaru' is progressing at a pace I didn't know possible until now. Sundar C is special. Very funny script. Super fun," Siddharth tweeted.

Meanwhile, Siddharth has two more Tamil films in his kitty - "Udhayam NH4" and "Kaaviya Thalaivan".
