It was Blood on the Sun (1945). There’s also a short scene in G-Men (1935) in which Jimmy is training for the FBI and taking a judo class. He’s a quick study. 
Oscar-winning actor Victor McLaglen (The Informer, 1935) was a champion wrestler and boxer before turning to acting, and taught both in a Hollywood “physical culture” school.
George Lazenby holds a black belt in karate, trained with Bruce Lee, and served as a self-defense instructor with the Australian armed forces before landing the role of James Bond (by breaking a stuntman’s nose during the fight-scene audition).
John Cusack has a black belt in kick-boxing.
James Caan is a 6th degree black belt in Gosoku Ryu karate.
As well as being a veteran of the Boer War and briefly provost marshall of Bagdad. Mentioned in dispatches!
He could have kicked all our asses.
I’m not surprised. Rogan commentates UFC fights, and he seems to know what he’s talking about. I gained new respect for Joe Rogan when he gave up pursuing his own comedy career and devoted his life to destroying Carlos Mencia’s.
Getting back to the OP, Patrick Stewart trained as a boxer.
There’s a picture somewhere of McLaglen standing next to Jack Johnson. They look like a couple of sequoias.
By all reports Basil Rathbone was a pretty good fencer.
Maynard James Keenan (lead singer of Tool and mastermind behind Puscifer) has studied Gracie Jiu Jitsu (he’s on the list linked above).
My BF – who teaches kung fu – just started taking Jiu Jitsu classes. I showed him the video on YouTube wherein a fan jumps onstage with Tool during a performance and tries to hug Maynard or something. (I’m not quite sure what the dude’s intent was, aside from being a drunken douchebag at a Tool show.) Maynard, without missing a word or dropping a note, took the guy down and got him in a submit position, where he kept the guy pinned to the stage so he could finish his song. The quality is crap, but the BF thought the whole thing was hilarious/pretty damn cool.
I don’t see Steven Seagal’s name on the linked list nor has it been mentioned in this discussion so far. Mr. Seagal holds an advanced ranking in Aikido and has, at times, been an instructor in the art.
French model Danielle Aubry landed a supporting role in Bikini Beach through her practice of savate. Apparently, she’s the Danielle who I’ve been wondering about regarding a certain “Tonight Show” clip with Johnny Carson.
Thank you for noticing. It’s a skill I’ve been honing for decades 
Debunk? I have neither the spare time nor the inclination. Hell, for all I know every statement on that site is true. My point (and yes there was one under that thin layer of snark) is about presentation; namely citing sources (a concept all dopers should understand) and weasel wording.
Here is a statement:
David Akers, a placekicker in the NFL (American pro football), has trained in jiu-jitsu and shaolin kempo since 2000.
Compare this to what we get from your link:

Bolding mine, of course. Do you see the difference?
And now, having expounded, I have a question for you.
Why so hyper-sensitive about a link that you probably just I-Feel-Luckied from google?
Wow, snarky twice without provocation.
I’m not hypersensitive about it at all; I think you’re projecting that.
The OP asked for some info, I found some info. If you want to make the claim that the info is no good, as you seemed to be doing, then I thought that perhaps you had more info. It’s okay that you don’t.
Mark Dacascos, currently “The Chaiman” on Iron Chef America, is the son of Al Dacascos, founder of the Wun Hop Kuen Do branch of Kajukenbo, and is a highly trained martial artist.
Robert Downey Jr. studies Wing Chun and was getting ready to test for his brown belt as of May 2010.
Writer Sean “Seanbaby” Reiley trains in Muay Thai and Jiu-Jitsu. In 2006 he responded to an open invitation from director Uwe Boll (who apparently has some boxing skill) to fight critics who didn’t like his films in a boxing ring. Boll reportedly did not answer.
As noted above, Ed O’Neill is a black belt in Gracie Jiu-Jitsu and Joe Rogan received a brown belt from both Carlson Gracie and Eddie Bravo. I believe Maynard James Keenan has a color belt from Rickson Gracie.
James Coburn did train in Jeet Kune Do with Bruce Lee, along with Steve McQueen, Kareem Abdul-Jabbar and a few other celebrity types. Most were likely “dilettante-ing” around, however.
Kris Kristofferson was awarded a Full Blue for boxing at Oxford University.
Off the screen, Mark Wahlberg is a skilled boxer.
Vladimir Putin is a 6th Dan in Kodokan Judo.
Lou Reed has studied Tai Chi Chuan since the 1980’s.
Wow! I can’t believe Boll still does that! That worked out so well for him 5 years ago! He’s a destroyer!
Yeah, Seanbaby’s “The Saga of Uwe” about the incident is pretty hilarious, and contains this bit of Nobel Prize winning trash talk:
“Uwe, learning that he wasn’t fighting a midget, asked for my age, height, weight, and fighting experience. I e-mailed this information, along with the reassurance that the Holocaust survivors got together and agreed he was the worst thing to come out of Germany. I figured this would make him mad enough to ignore that I’m several weight classes above him in F-List Celebrity Boxing. It didn’t. After reading my stats, he suddenly couldn’t make it on the show. There was a short discussion of flying me to the set of Postal, but I’m not holding my breath. Uwe is the one making the Nerd Combat rules, and rule No. 1 is: Uwe only hits people who don’t explode Uwe’s face when they hit back.”
