The three actors play brothers reconnecting with each other on a train trek across India in the new Wes Anderson film.

"To me, I feel like we felt like brothers. I think there was a genuine affection and -- may I say love? -- for each other there," Schwartzman told UPI in New York. "It could have gone much differently had we maybe made the movie in Burbank, Calif.

"When you have your own car, your favorite restaurant, your bed, your dog -- the things that make you you and make you comfortable -- when you have those, it's very easy for actors to wander off towards them. ... An actor's tendency is not to stay on the set," he added.

Schwartzman said the actors did not have trailers on the Indian set and everybody stayed at the same hotel.

"There was nowhere to go. So we were all together, all the time."

Asked how Wilson is doing now, weeks after he reportedly attempted suicide, Schwartzman politely said, "I'd rather not talk about that."
