The producer-director is excited to produce the sequel to the 1997 superhit comedy, which had Salman Khan in a double role alongside Karishma Kapoor, Rambha, Kader Khan, Shakti Kapoor.
The sequel stars Varun Dhawan in the double role, originally played by Salman.
"It will be interesting to have him (Salman) in cameo appearance. We would definitely want it. It depends on how the script shapes up," Sajid told PTI.
"Cameos are good only if we have actors do it as per the requirement of the script otherwise no point just having someone for the heck of it."
Sajid said work on the script of "Judwaa 2" is still on and the film may hit the floors next year.
"Almost 70-80 per cent of the film ("Judwaa 2") is written. We should be ready by Diwali. We may roll in next year," he added.
David Dhawan, who had helmed the "Judwaa", will direct the sequel.
Sajid shared the film will have two heroines.
When quizzed if the female lead will be picked up from the young crop of actresses, he said, "It depends on script and once it is complete we will let you know."
There were reports that Alia Bhatt and Shraddha Kapoor will play the two heroines in the sequel.
