LOS ANGELES, Calif. -- Zac Efron turned down a role in the 'Footloose' reboot in order to pursue 'the unknown,' but one thing the actor is certain of is how happy he is that Chace Crawford is taking over. 'I'm ecstatic for him,' Zac told Access Hollywood's Shaun Robinson on Sunday at the MTV Movie Awards when asked about the 'Gossip Girl' star taking the role he left vacant.
