<p>The 32-year-old star plays real-life surviver Ralston, who was forced to amputate his own arm after he became trapped under a boulder during a hike in Utah in 2003, E!Online reported.<br /><br />But the 'Slumdog Millionaire' director says he thought Franco was high on drugs when they met for the audition.<br /><br />"We saw a number of guys and he wasn't the obvious choice because he's not a look-a-like and he's an urbanite really. He's a city guy like me. He's not a wilderness guy. I wasn't sure at first. We met him and he was so relaxed - he looked stoned to me," Boyle said.<br /><br />'Milk' star too admits that he won the role because of the memorisation skills he picked up during his stint on American soap opera 'General Hospital'.<br /><br />"I did have to read for it. (Boyle) had me fly out to LA He didn't give me any material to prepare and when I got there he gave me a page-long speech. He asked if I could memorise and do it right away, which normally would have been difficult but I had just been working on a soap opera, General Hospital.<br /><br />"I had to memorise like literally 70 pages a day so that little speech was no problem. I don't think he knew at the time that General Hospital helped me get the role," Franco said.</p>
