This is an idea I ran by a fellow Trekkie awhile ago. An “Ed Wood” like movie about the behind the scenes of TOS. Satirize it from a place of love, focus on the drama between the cast and the antagonism between the studio and Gene. Quality movie material!
I have not but I’ll have to check it out. William Shatner and Leonard Nimoy being time travellers from the future would certainly be a twist!
