I remember seeing "Roll, Freddy, Roll" when it first aired on December 17, 1974; I had just begun junior high school in Lansing, Michigan.
Seeing this film again would bring back many great memories; unfortunately, the last time I saw "Roll, Freddy, Roll" was in 1987 when an independent station here in Detroit ran it. Naturally, the station cut the film in order to fit the time slot (without commercials, "Roll, Freddy, Roll" ran about an hour and 40 minutes).
I discovered Disney now owns "Roll, Freddy, Roll;" in mid-1995 they purchased ABC, whose former ABC Circle Films division produced the film (ABC Circle Films was later responsible for "Moonlighting").
In unity there is strength, and the more requests Disney receives about "Roll, Freddy, Roll," the quicker they'll dig into their vaults, unearth it, and put it on DVD!
(Postscript, May 12, 2020:
I discovered about five years ago *MGM* now owns the rights to "Roll, Freddy, Roll." It's part of an ABC Films portfolio MGM distributes for all media including such other ABC Circle Films made-for-TV movies as "Can Ellen Be Saved?" and "The Day After," as well as such ABC Motion Pictures theatrical films as "Silkwood." So all I can suggest now is to try contacting MGM and/or Universal Studios Home Entertainment, who now distributes all MGM product - with the exception of the pre-June 1986 MGM films, which are owned by Warner Bros. - on DVD. If either or both companies are hounded enough, then hopefully they'll put "Freddy" on DVD.)
