The 22-year-old actor admits that he and brother Dylan 'are not as lovey dovey as the brothers in the movie' so that he 'was thinking of him a lot during filming.'
Zac Efron relished the loving relationship with his onscreen sibling in "Charlie St. Cloud" because he and his real-life brother are too masculine to open up emotionally. The 22-year-old actor gets on well with younger sibling Dylan and thought about their friendship often while he was on set of the emotional drama.
And Efron used the opportunity to be affectionate with his onscreen brother, played by Charlie Tahan, as a substitute to professing his feelings for Dylan. He tells BBC Radio 1, "We're not as lovey dovey as the brothers in the movie. We're pretty competitive and we're dudes."
"I think that's the reason it was fun to have a fake little brother because I could really go up to him and say I love you and all that stuff because me and my brother don't do that - it's unsaid. We're dudes so you kinda can't! I was able to let all of that come out - I was thinking of him (Dylan) a lot during filming."
