The British filmmaker admits he couldn't have coped without the Oscar winner's support on the set of the new movie, in which she plays the late Apple co-founder's right-hand woman and marketing executive Joanna Hoffman, because she was always on hand to fix any problems.

He told PEOPLE magazine: "Kate is a wonderful partner on a film. She would fix everything - you know, extras, any problem, even people crying.

"She's hilarious and fun to hang out with. And she is not afraid to offer her input into a situation."

The 40-year-old actress' co-star Seth Rogen also appreciated having her on the set.

He explained: "She's hilarious ad fun to hang out with. And she is not afraid to offer her input into a situation."

But Kate, who has three children, Mia, 15, Joe, 11, and 22-month-old Bear, insists she tried not to interfere too much.

She said: "I don't go around sort of mothering everyone, but I make it my job to find out exactly what's going on all the time."
