Over the past few days, the cast of "Star Wars: Episode VII" has been taking the ALS ice bucket challenge -- with Mark Hamill the latest to get soaked.
And as you can see in the clip above, he's looking more like Obi-Wan Kenobi than Luke these days.
Hamill was challenged by fellow cast member Daisy Ridley, whose role in the upcoming film remains a mystery:
Even Harrison Ford got in on the act. His ice bucket challenge is the only clip on his YouTube page. (Who knew Harrison Ford even had a YouTube page? And can anyone picture Indiana Jones searching for cat videos?)

Other "Star Wars" figures who've accepted the challenge include director of the current film, J.J. Abrams, director of the upcoming spinoff film, Gareth Edwards, and actor Oscar Isaac.
"Star Wars: Episode VII" is set for release on Dec. 18, 2015.
The ice bucket challenge is being used to raise money and awareness for amyotrophic lateral sclerosis, a.k.a. Lou Gehrig’s disease. The ALS Association said Monday that this year's challenge has raised $79.7 million, compared to $2.5 million during the same period last year.
