Tom Hanks makes a point of dining with his Toy Story co-star Tim Allen at least once every two months because he is fascinated by the comedian's mind.

The Oscar winner insists the actor is the perfect dinner buddy, because he has an exhaustive knowledge of trivia.

Hanks explains, "He and I will have a sit down summit about everything that's going on in our lives.

"We had lunch and talked for two and a half hours. Tim's brain is like an engineer's. He can talk about how air-conditioning units are made wrong. He actually designed a prototype of a drill he tried to sell to... Black & Decker or something. I swear to God, that's the way he operates."
