Mike Stemmle is a man who knows Sam & Max. He worked on Hit the Road, Freelance Police, at Telltale, and on the upcoming This Time It's Virtual.
He appeared yesterday on a Twitch stream to talk mainly about Escape from Monkey Island, but of course the questions covered his entire career and his work on the freelance duo.
It's a great interview hosted by Laura Cress, who runs her own adventure game podcast. Check out the archived stream here and skip to the 43 minute mark for when Mike appears.
