Tom Hanks had a "wonderful" time working with Sandra Bullock.
The pair star together in 'Extremely Loud and Incredibly Close' and forged an instant bond as soon as they met up to discuss the script.
He said: "Sandra Bullock, I'd met her at award shows and things like that before briefly, but the very first thing we did in rehearsals was that Sandra, Thomas [Horn, who plays their son] and I made lunch, we got together and just made lunch, for the three of us. We made some spaghetti, salad, garlic bread and what not.
"And I could not discern any true effort between that day of rehearsal, months before we started making the movie, and the moments where we were actually working with a camera rolling. It's so fluid with her. She is wonderful."
Tom was also full of praise for his young co-star, saying Thomas, 13, was very impressive at tackling such a complex film.
He told website FlicksandBits: "He's the star of 'Extremely Loud and Incredibly Close,' he had to show up for rehearsals, for coaching, for research, or for actually shooting the movie - at what could be described as a back breaking schedule.
"But he had such unbridled enthusiasm for every moment of that, and that's a testament to a certain degree of character. He was pretty spectacular."
