Before Dan Shea became a stunt coordinator, he was a stand-up comedian for 10 years.
He is the father of actresses Joey Shea and Stephanie Shea.
He has appeared in episodes of three different series with Richard Dean Anderson: MacGyver, Stargate SG-1, and Stargate Atlantis.
An eye injury (obtained playing hockey) prevented him from playing professional hockey and he turned to stunt work and acting instead.
Dan Shea: (about getting the job of Siler on Stargate SG-1) Martin Wood was doing an episode and they were reading for this guy Siler and said I should read for him. So I went upstairs and Tasha, the extras girl on set, and I did my lines over and over again - and it wasn't happening. I don't know why. Sometimes it feels right and sometimes it doesn't. So I went up to the room and there's Brad Wright and Martin Wood and I just went back to my old stand-by of joking around, so I made everybody laugh. I thought, 'This is pretty cool, if they need somebody funny they'll hire me.' Unfortunately they didn't want anyone funny, they wanted Siler. So I went down on the set and Greenburg grabbed me. "Why did you do that? You made yourself look like a fool. They wanted to cast you if you were even half-way decent so get up and do it again." So I had to get the sides back and memorize it, because the words, the techno-stuff wasn't happening for me, sometimes it flows, other times it doesn't. So I went up and I did it straight. A couple of hours later then I got hired and then it just kept going and going.
Dan Shea: (about stunt coordinating) Every day is serious. When there is fire you are responsible for no-one getting hurt, you are responsible for the illusion of somebody potentially being unsafe, you are open to extras claiming they were put in danger. There's constant pressure all the time but the effects guys are so great they make everyone's job so much easier.
