The Greatest: Pierce Brosnan and Susan Sarandon share a passionate embrace in new movie, 'The Greatest'

Irish actor, Pierce Brosnan, was in London this week and told reporters he found it exceptionally difficult making his new movie, "The Greatest," because it brought up strong emotions surrounding a near-fatal car crash his son was involved in.

Brosnan, 56, said after initially reading writer-director Shana Feste's script, he tossed it under the bed.

"I found it too heavy," he admitted.

After a little persuasion he agreed to do the movie but knew it would be a challenging one.

“This young woman had written this beautiful script, called "The Greatest" and it’s about the loss of a son and my son, Sean, I almost lost him a number of years ago in a terrible accident,” he said.

“You get that dreadful call at 4.30 in the morning and he got airlifted out and he survived, and this film is about the loss of a son and the family coming together again." he added.

“When I read it I said, ‘No, I don’t wanna go there, it’s too heavy,’ and threw it under the bed and then my partner… said, ‘Look, check it out again, You’ve gotta do this,’ so I read it again and said, ‘OK, let’s go for it.’”

Brosnan added: “It’s a beautiful film… It’s a really tender, powerful film.”

"The Greatest" will hit movie theaters on April 2.
