this article made me chuckle because I'm 99.9% sure every one of us have been in a very similar situation especially me http://uk.movies.yahoo.com/man-steel-su ... 00613.html
'Man of Steel' actor Henry Cavill has revealed he almost missed out on the Superman role because he was playing 'World Of Warcraft'. Didn't expect that did you...
In an interview with GQ, the British actor discussed his love of video games, recalling how the casting call from director Zack Snyder interrupted a gaming session: "I saw it was [Snyder calling] but the thing is, you can't save 'World of Warcraft', you can't pause it. It's live."
As you can guess, Cavill eventual called the director back and took the part. After he'd finished playing of course.
