Matthew Fox has revealed that he did not enjoy losing the weight for his new role in Alex Cross.
The actor takes on the role of bad guy Picasso in the new Alex Cross movie, which sees Tyler Perry take over the title role.
Fox had to lost 44lbs for the part and while he enjoyed the finished result it was not much fun getting there.
Speaking to Men's Health the actor said: "When I read the part, it felt immediately that my character [serial killer Picasso] is burning energy on almost a hyper level.
"Without needing to spend any time in the gym he would just look like that... almost disturbingly vascular and tendony, and f**king just... weird. That would come from an enormous amount of energy burning inside this guy."
"If I'm honest, sometimes I f**king hated it. I guess if you removed the 'result' part of it then I can't say I enjoyed it."
After wrapping up Lost in 2010 Fox seems to be focusing his attention more on film as we will be seeing him back on the big screen next year in World War Z.
Alex Cross is released 30th November.
