An MST3K two-fer, George Milan played "Gen. Nelson" in experiment #319 - War of the Colossal Beast and, most importantly, "Merlin" from experiment #1003 - Merlin's Shop of Mystical Wonders!

Although he doesn't have much of a biography available online, he found pretty steady work in smaller film roles over the years (including appearing as Averell Harriman in the James Woods vehicle, In Love and War), and was (according to IMDB at least) a native son of Wisconsin.

He passed in 2010 at the age of 91.
