The 44-year-old, who was here for a mobile launch, denied speculation that the untitled project is based on William Shakespeare's tragedy "King Lear".
"Yes, I'm working with him. I don't know the script, but I don't think its 'King Lear'. It's something else, so I'm excited to be working with him again. I think we do really good work together," Saif told IANS here.
The film will mark the first time he will be working with his wife Kareena Kapoor Khan's former beau Shahid.
Asked about his future projects, Saif said he has also signed on to work with Sujoy Ghosh and Vikramaditya Motwane.
"These are the three films (including the one with Bhardwaj) that I'm looking at at the moment," he added.
Meanwhile, Saif will next be seen in "Phantom", which also stars Katrina Kaif. The upcoming counter terrorism drama film has wrapped up shooting and is all set to release on August 28.
