New ‘X Men’ flick a hair-raising experience for McAvoy

James McAvoy insisted on wearing hair extensions in 'X-Men: Days of Future Past'.

The Scottish actor is a keen enthusiast of the 1970s - in which the new film is set - and was so determined to authentically portray his character, Charles Xavier's style during the era, he asked producers to give him extensions to create a free-spirited, long-haired look.
