Liam Hemsworth and Jennifer Lawrence do their best Star Wars impressions…including Chewbacca's groan!

It's Star Wars day in movie land, which means that some folks will be taking the opportunity to show off their best Chewbacca imitations. Even The Hunger Games cast got in on the action.

Watch Liam Hemsworth, Jennifer Lawrence and Josh Hutcherson doing their best impressions of the iconic hairy character above. Sorry Jen, but you could use a bit of practice.

Keep watching to see Tom Hiddleston taking on the gruff tones of Darth Vader's voice in the clip from MTV.

Star Wars: The Force Awakens is out now in Australian cinemas.
