Jane Seymour found working with Robert De Niro to be "pleasantly" overwhelming.
The 69-year-old actress teamed up with the Hollywood icon to star in the family comedy film 'The War with Grandpa', and Jane has admitted to relishing the experience.
She said: "I was very pleasantly overwhelmed. Mr. De Niro was lovely.
"He literally just turns the bright lights on the minute they say action. And most of the rest of the time he keeps himself to himself pretty much."
Jane has one particularly fond memory of working with De Niro and the rest of the film's cast, which includes Uma Thurman, Cheech Marin, and Christopher Walken.
She told Us Weekly magazine: "While I was working with him and we were doing a trampoline scene, we were all hanging out together. Somebody should have filmed what was going on.
"You can imagine: Christopher Walken, De Niro, Cheech Marin and myself. We were all [sharing] the war stories and the funny stories.
"It was the old fogies reminiscing and laughing, and, of course, with Christopher Walken, everybody feels that they have to do a Chris Walken imitation and he does by far the best imitation.
"So it was somewhat redundant."
Jane also revealed that in spite of their advancing years, some of the movie's star-studded cast members were still required to perform stunts.
She explained: "I’m sure Mr. De Niro and Chris Walken have the bits that don’t function as well.
"Yes, there were some stunt doubles there, but you still have to land. So I had a stunt girl who threw herself against the wall and then landed. Well, I still had to throw myself against the wall and land and be trampled."
