I don't see where the problem is?
Every movie we Americans have with Germans speaking English use that kind of accent. Heck, look at our own governor of California. If he doesn't have a horrible English accent, I don't know who does.
Horribad English accents happen all the time. Fran Drescher, Paul Purdohme, Jerry Sienfield, people from Minnesota, ect. I don't see why anyone would get bent out of shape about some German guy having a heavy German accent. I would assume that if I went to Germany and learned German, that everyone there would have a hard time understanding my American accent for German. English is used too broadly to get offended by someone not speaking it properly...Its the world's trade language, so your not always going to get a native speaker.
Back from the dead, I'm afraid.
