Elizabeth Banks fails miserably at Chewbacca and C-3PO impressions

The force is strong for Elizabeth Banks -- just not for her impersonation skills.

The Pitch Perfect 2 star stopped by The Ellen DeGeneres Show on Tuesday to explain her two sons' fascination with Star Wars and showed off her horrible (but hilarious) character impressions.

"They really don't know anything about Star Wars," she told the host. "I don't know how Star Wars is doing it but they possessed my children with Star Wars."

The mother of two then explains Magnus and Felix got tooth brushes with Anakin Skywalker and Darth Vader on them and that's when the obsession began.

"I started telling them the story about Chewbacca and C-3PO and R2-D2 and getting into all the details," she explained. "I started doing the voices. "

Then the actress let out her best impression of Chewbacca, stating "I don't really do a great Chewbacca to be honest with you."

Banks went on to explain that her son's recommended she just look up the characters' voices on the Internet instead of doing them.

She also showed off her C-3PO and R2-D2 impressions, which proved to not be much better.

Although Bank's impressions weren't that impressive, the new Star Wars: The Force Awakens trailer is. Check out the sneak peek at the film below.
