Actors Shah Rukh Khan and Nawazuddin Siddiqui's busy schedules are reportedly leading to date clashes, which in turn is delaying the shooting of their upcoming film "Raees".

After working with Salman Khan in "Kick" and "Bajrangi Bhaijaan", Nawazuddin is now ready to share the screen space with Shah Rukh Khan in "Raees".

However, the two actors are busy with their other projects as well and their dates have not been matching for the shooting of "Raees", Pinkvilla reported.

According to the report, Shah Rukh has been busy these days with the shooting of "Dilwale" in Iceland, while Nawazuddin is having a hectic schedule for some short films and has other prior commitments.

Apart from "Dilwale" and "Raees", Shah Rukh has another film lined up, titled as "Fan". Nevertheless, the duo are trying to match with each other's timing and commence shooting for "Raees".

While, Shah Rukh's last film was "Happy New Year", Nawazuddin impressed his fans with his performance in the film "Manjhi-The Mountain Man".

Directed by Rahul Dholakia, "Raees" also marks the debut of Pakistani actress Mahira Khan. Shah Rukh Khan will be seen playing the role of a merciless bootlegger.

Meanwhile, Shah Rukh's "Raees" and Salman Khan's "Sultan" will reportedly have a clash next year as both the films are slated to have 2016 Eid release.

Earlier there were rumours that makers of "Sultan" have shifted the release date from Eid to Diwali, but later Yash Raj Films confirmed that there was no change in the release dates.
