Mumbai: The Hollywood actor, Leonardo Di Caprio is apparently having trouble allotting dates to King Khan for their film Xtrme City with Martin Scorsese.

Shahrukh Khan may be doing everything to ensure that his upcoming film RA. One hits no roadblocks. But the same cannot be said for the movie that is being touted as the superstar's foray into Hollywood.

Earlier this year, it was reported that King Khan had hit jackpot by managing to rope in the legendary filmmaker Martin Scorsese to co-produce his dream project, Xtrme City.

But alas, the film already seems to be facing a major glitch.

Apart from Scorsese and SRK, Xtrme City was to include actor Leonardo Di Caprio, but now apparently, the makers are not able to zero in on a date for the Hollywood star.

Adds a source, "The script has been locked and right now they have been zeroing in on everyone's dates for the project. SRK, Scorsese and even writer Paul Schrader's dates are pretty much in. The problem is Leonardo Di Caprio's dates haven't been decided upon."

The actor is busy filming the Great Gatsby (which is incidentally Amitabh Bachchan's first Hollywood project) at this point and nothing really can be finalised unless his dates are confirmed.

For a film that boasts of such heavyweights, it's little surprise if delays are part and parcel of the process. It was during the Berlin film festival in February that SRK got a chance to meet the Oscar winning director and actor and discuss the project.

Interestingly, it is said that Scorsese's interest in Indian cinema was one of the main reasons he agreed to come on board for this film.

Adds the source, "Now, we all know that Scorsese and Di Caprio are thick as thieves and always work together. So it's very essential that he comes on board for this one as soon as possible."

So despite all the dilemmas, if this project does manage to take off, there's little doubt that it may become even bigger than SRK's superhero thriller!
