Actor Matt Damon blames his age for forcing movie makers to extend filming for THE BOURNE ULTIMATUM - after he took so long shooting fight scenes. The star found filming action routines so exhausting, movie bosses were forced to extend the movie schedule by two days at an extra cost of GBP300,000 ($600,000). He says, "The fighting stuff did take its toll. In the first movie I was 29 and in this one I'm 36 and definitely feeling my age."
