Mark Wahlberg says he was worried about his character falling for an ape in the 'Planet Of The Apes' remake.

But his concerns were eased when he saw his co-star and love interest Helena Bonham-Carter in her make-up as the ape princess, Ari.

He said she looked "mind blowing" when made up as an ape.

The 'Boogie Nights' star said, "Once I saw Helena I had no problem portraying those feelings."
