“The Hangover” star said “he understands the importance of life that we tend to forget on a daily basis. But I have the feeling he was like that his whole life not just when he was plagued by this horrible disease.”I think when it’s not personal and you can’t relate to it, you tend to not take action. But I dare anybody to read Anthony’s story and not care about him right away.”

The hollywood actor whose dad died of cancer four years ago admits that not helping Anthony wasn’t an option for him.

“Anthony just has a genuine love of every moment that he’s alive and I find that to be very compelling And especially heartbreaking because he’s afflicted with essentially terminal disease.” Actor said.

The 24-year-old Anthony Michaels was very impressed with the “Silver Linings Playbook” star’s ‘selfless’ attitude.

“He was a real humble guy and he was very easy to talk to as i didn’t think he was going to be as selfless as he was so it was a nice surprise to say the least.” he said.
