The "Bang Bang" director is teaming up with Dutt for the first time.
"We will be working on a film soon. It's an action film (yet to be titled) with elements of thrill. We will begin shooting in summer," Siddharth told PTI.
He revealed it is not a multi-starrer. The project is likely to be the first for the 56-year-old actor after his jail term.
Asked if there is a leading lady romancing Dutt in the film, Siddharth chose not to give out any details.
Dutt will also be seen in director Umesh Shukla's untitled film with a social theme, Indra Kumar's third instalment of comic capper "Dhamaal" and third part of "Munnabhai" series.
