Ashton Kutcher has had quite a few personal issues over the past year, with a split from wife Demi Moore provoking worries for his now ex-wife, and he doesn't seem to have left his cares behind when filming new movie 'Jobs'.
The film is a biopic of the Apple founder Steve Jobs, and Kutcher does bear an uncanny resemblance to the computing mogul, sharing Jobs' imposing height and angular looks.
Due to his less than sunny demeanour, Kutcher also looked to have taken on another aspect of Jobs' character, a harsh uncompromising determination that has led to Apple becoming one of the world's leading tech companies.
However he did share a joke with co-star Ahna O'Reilly that seemed to raise his spirits, ridding himself of his care worn look for a brief period.
