Simon Pegg has joked Tom Cruise is a ''sadist'' on the set of 'Mission: Impossible 6' because he constantly brings cakes and biscuits onto the set when he knows everyone needs to stay in shape.

The 47-year-old British actor stars as Benji Dunn in the action spy franchise alongside Cruise - who stars as Impossible Missions Force (IMF) agent Ethan Hunt - and the two are currently shooting the newest installment.

Pegg says Cruise is a ''great guy to work for'' but his penchant for constantly bringing sweet treats to work for the cast and crew makes him suspicious of his motives because everyone has to be in top physical condition for the stunts.

Speaking on 'Jamie And Jimmy's Friday Night', Pegg said: '''Mission: Impossible' is always fun because it's like getting on a ride - you know, because it's a Tom Cruise movie. I've never been in better shape my whole life since I've been doing these movies because I train a lot and I eat right. He's a great guy to work for but he's a little bit of a sadist. He will always buy you cakes and biscuits. I think he's testing me. He likes torturing me with cake.''

Christopher McQuarrie is producing alongside Tom, Frederick Schmidt, Don Granger, J.J. Abrams and David Ellison and Dana Goldberg from Skydance Productions.

However, Jeremy Renner will not be reprising his role as IMF Field Operations Director William Brandt due to a scheduling clash with 'Avengers: Infinity War', in which he will be playing Hawkeye again.

Big screen Superman Henry Cavill has also been added to the star-studded cast for 'Mission: Impossible 6'.

Angela Bassett - known for her role as Tina Turner in the biopic 'What's Love Got to Do with It' - has reportedly jumped on board the project.

It's not yet known who the brunette beauty will play but Cruise will be back as the globe-trotting secret agent who always finds himself in tricky situations

Rebecca Ferguson, Ving Rhames, Alec Baldwin and Sean Harris are all returning for the next instalment of the franchise.

The film is scheduled for release in July 2018.
