Pre-production on 'M:I6 Mission: Impossible' has been halted due to Tom Cruise's salary negotiations.

The website added that two different reasons have been given for the hold-up, the first is that the studio wants Tom and the other producers to cut their fee and the second is that Tom wants a raise to equal what he got paid for 'The Mummy' from Universal while Paramount would prefer to pay him what he got for the fifth 'MI' movie.

However, the salary negotiations are unlikely to affect filming, which is not due to start until January.

'Mission: Impossible Rogue Nation' had a budget of $150 million and grossed $682 million worldwide.

Meanwhile, Tom is currently working on 'The Mummy' reboot in London, in which he plays Navy Seal Tyler Colt.

The story follows Tyler's mission in the Iraqi desert to find a group of terrorists hiding out in a bunker, but he soon finds they are nothing more than some grave robbers who have all died upon entering a mysterious bunker.

Tyler and his team discover the bunker is actually a centuries old tomb and mayhem erupts as all the Navy Seal members start turning on one another.

After making his way deep within the tomb, Tyler finds a black iron sarcophagus marked with Egyptian symbols and is compelled to open the sarcophagus and release the mummy inside. But after touching the relic, he is immediately stabbed in the palm with a star shaped symbol cursed with visions of Ashurbanipal, King of Assyria.
