I'm definitely late to the game posting this, but that doesn't make it any less deserving. I've been hearing great things about it.
Read a great piece about the band & the film by Chris Morris over at the Oxford American: "My first encounter with Big Star was in the mid-’70s, when I worked as a disc jockey at an FM station in Madison, Wisconsin. In the manner of the day, it was a completely “free-from” outlet—its official handle was “Radio Free Madison”—and its programming was wide open. There was no playlist and just one basic rule, almost laughably righteous in the face of Top 40 radio’s constant repetition: if a song was played by one jock, another jock could not repeat it during a subsequent shift that day. To police this policy, each of the seven thousand or so LPs in the station library contained a log sheet; when a DJ played a track, they had to note the date on the log so that others wouldn’t spin the cut within the same 24-hour period." Continued here.
Also of note is a new doc about influential record store (in Denver), then record label (in Chicago), Wax Trax. It looks like it may be pretty good although I was never a disciple of their entire catalog. They definitely have their place though, and perhaps the story is interesting enough for a film. We'll see (hopefully)!
