Watch: Liam Neeson strips down to pink briefs for cancer research

Taken star Liam Neeson has... taken it all off to help raise money for cancer research.

Appearing on Ellen in a fuzzy pink robe, the plan was for him to have a bucket of water dunked on him for US$10,000.

Well, Liam wanted to raise the stakes and do his bit for charity, revealing a pair of neon-pink briefs and willing to strip down if Ellen was willing to double to money on offer.

And she was!

Liam pushed his luck and asked if she wanted his briefs off too.

"We get fined if you take those off. I mean, some people might enjoy it, but," Ellen joked.

Check out Liam getting dunked in the video above. Not bad for a 60 year old!
