George Clooney wore the same attire every day on the set of 'Money Monster', according to Jodie Foster.

The 53-year-old star directs the new crime thriller and has given a behind-the-scenes glimpse into life on set with George, admitting the Hollywood hunk - who is known for his love of pranking his co-stars - would dress very casually from day to day.

Jodie said: "This was a tough movie and he had a lot of dialogue squeezed into one time frame, so there wasn't the time for pranking. But George is great.

"One of the things I love about him most is, he wears the same T-shirt and the same jeans pretty much every day."

But Jodie admitted George undergoes a remarkable transformation by the time he needs to promote the movie.

She said: "He has like 10 of the same things, and is always on time. He's a work bee. But then I'll see him at a junket with those eyes and he looks fabulous."

The actress-turned-director also worked with Julia Roberts on the new movie and said she relished the experience.

She shared: "She's so extraordinary. I'm in awe of her, I have to say. It does make it a little bit hard to work with her because I have to get over the fact that I'm sitting in front of Julia Roberts.

"Her stuff goes very fast but she's incredibly prepared. I feel so lucky that she landed on our doorstep. I only got her for eight days, yet she is on screen for the whole film."

'Money Monster' centres on financial corruption on Wall Street and Jodie admitted she loved directing a movie that deals with wrongdoing in the corporate world.

Jodie told Total Film magazine: "There are so many reasons I love the film. The backdrop of the finance world and the world of the media with little hints of satire are nice, but the real reason I get involved in movies is the characters and the issue they have that somehow I am trying to work out in my own life."
