Blood Rayne: The Third Reich (2010)

Half human, half vampire Rayne fights Nazi's in World War II, starting by releasing the human cargo en route to the death camps and slaughtering the Nazi's.  Nazi commander Brand accidentally gets turned into a vampire, but that's just part of the collateral damage that occurs when Rayne and freedom fighters show up at the same place at the same time.

Unfortunately Brand decides that he should use Raynes blood to make Hitler immortal.  So while Rayne's hunting him, the Nazi's are hunting her, complete with Clint Howard doing a bad Peter Lorre imitation. He may not have been trying to do Lorre, but that's what it sounds like.

You'd think Nazi's and vampires would mean something fun and exciting would occur. You'd be dead wrong.  It's pretty slow moving and the dialogue is awkward.  Also there are ridiculous sex scenes, including one of a freedom fighter and Rayne getting it on while being transported to a concentration camp.  Because nothing says arousal like a trip to the gas chamber.

Ridiculous dialogue:

• "He's not just a vampire, Rayne.  Now he's a vampire with an entire German army behind him."
• "Enough!  You told me. You assured me... that you would help me heal.  You gave me your assurances."
