German’s first work was on stage in Peter Pan and Oliver. She made her feature film debut in the 2000 romantic comedy Down to You, where she had a small role as a lovestruck woman.

In 2002, German co-starred in the romantic drama A Walk to Remember with Shane West and Mandy Moore, based on Nicholas Sparks’ 1999 novel of the same name. She played Belinda, who breaks up with Landon Carter (West). She then appeared in the crime/horror film Dead Above Ground, the drama A Midsummer Night’s Rave, and the TV movie The Lone Ranger, where she had both smaller and bigger roles. In 2003, she auditioned to star in the remake of the classic 1974 horror film The Texas Chainsaw Massacre, but the role went to Jessica Biel, and German won the role of The Hitchhiker.

In 2016, German began appearing with Tom Ellis in the former Fox fantasy comedy-drama Lucifer, as Detective Chloe Decker. She plays the role of an LAPD homicide detective who finds herself both repulsed and fascinated by Ellis’s character, Lucifer Morningstar, who was tired of his “job” as the Lord of Hell and relocated to Los Angeles.
