Dave Franco feels it is "finally the right time" to work on a movie with his brother James.
The 32-year-old actor had previously refused to star alongside his older sibling because he didn't want people to think he was "riding his coattails" but after Dave managed to cement his position as a star in his own right, he was happy to take on the role in 'The Disaster Artist'.
Dave said: "It was finally the right timing. For the first 10 or so years of my career, I just wanted to do my own thing. I wanted to make a name for myself, and as much as I love him and respect him, I just wanted it to be separate.
"And after a while, it's like, I feel like I'm standing on my own two feet, [so] I was like, 'I don't care what people are going to say [or] if they think I am riding his coattails.' I know that I have been true to myself. We had a really great time, have very similar sensibilities and are hoping to work on a lot more things together."
Whilst James added: "He has turned me down a couple of times, yes. Brothers should stick together! ...
"I knew from the beginning as I read the book that Greg [Sestero] had written with Tom Bissell that I wanted to tell this story - that it was an amazing story about dreamers and outsiders, but with this surface level that was so bizarre.
"But I also knew that I wanted to play Tommy and that I wanted Dave to play Greg - that we would have the right dynamic. So, I asked him and he finally said yes."
Dave's wife Alison Brie is also in the film and it was James' idea to have her on board.
He told Entertainment Tonight: "When you are working with family and a bunch of friends, it makes it really easy as an actor, because you feel comfortable with everyone, so you feel comfortable taking risks that you may not take otherwise ... knowing that no one is going to judge you. I think our best work is with our best friends and family."
