There's a video interview here:

where you can clearly see his scar on a couple of the clips, particularly if you have broadband and select the 'DSL oder Kabel' option. You can also right-click on the movie and zoom to Fullscreen. It's a german site (Viva) and the interview is pretty old now (just before the release of AROBTTH).
