"It is too early...We have not yet decided. We are waiting for 'Bol Bachchan' to release. So till July end we will not finalise. After that we will take up a call on that," Rohit said.
'Chennai Express' is a romantic film with Shahrukh in the lead. Though the lead actress is yet to be finalised, rumours are rife that Deepika Padukone or Kareena Kapoor may star opposite King Khan.
Kareena and Shahrukh were paired opposite each other in 'Asoka' (2001) and 'Ra.One' (2011), while Deepika made her acting debut opposite Khan in 'Om Shanti Om' (2007).
'Chennai Express' is slated to be a total commercial film in "Rohit style". It is the story about a man who travels from Mumbai to Rameshwaram and what happens during the journey.
Meanwhile, Shetty's 'Bol Bachchan', starring Ajay Devgn, Abhishek Bachchan, Asin and Prachi Desai, is set to release on July 6. It is inspired by the 1979 comic flick 'Golmaal'.
On similarities between 'Golmaal' and 'Bol Bachchan', Shetty said, "You will have to wait and see the film and tell me."
Megastar Amitabh Bachchan is set to recreate his famous entry scene in the song 'My Name is Anthony Gonsalves' for 'Bol Bachchan'.
The song in his hit movie 'Amar Akbar Anthony' had showed Big B popping out of a life-sized egg. The makers have recreated the scene for title track video of 'Bol Bachchan'.
The 69-year-old actor has lent his famous baritone for the track and the song will also feature some of his evergreen iconic dialogues from the film. "He has sung the song...We had fun doing it," Shetty said.
