His last co-production "Himmatwala" was a remake, which failed to enthuse the box office.
Confirming the details about "Humshakal", Bhagnani told: "I am making 'Humshakal'. It's a fresh film and not a remake. The film will be directed by Sajid Khan and it will have Saif and Riteish in the lead. The film will go on the floors by August."
"We have not yet finalised the leading lady, once we finalise the leading lady, we shall make an official announcement," he added.
Meanwhile, the filmmaker is also planning some new film for his son Jackky, whose "F.A.L.T.U" and "Rangrezz" bombed at the box office.
"We are planning something for Jackky as well but it's too early to disclose anything right now. Just give us some time and we will make an official announcement," he said.
