Greetings, hopefully I posted this in the proper place, I didn't notice the topic posted elsewhere.
I found this on RDA's website - an interview with RDA dated 11/27/2016 - it looks like it's from his recent trip to France:Link to article
He was asked why there was never a MacGyver movie, and responded "I couldn't say. Someone has the rights. Apparently, there have been discussions to make a movie. A new TV series was produced but it was not very well received."
Not sure if he means the one currently running with Lucas Till, or perhaps a reference to Young MacGyver with Jared Padalecki (a TV movie).
