In case anyone is interested, it will be on HBO again - Sunday morning (4/4/21) at 12:20 a.m. Eastern.
Way back, I saw it in the theater, but then recorded it on HBO, in short segments watched the whole thing once, but then kept it, presumably forever.  Then, I had to switch to the XFinity cable box and no longer had it.  I've been waiting for several years to get it again.  Other channels have had it, but I think they all have commercials, and I assume they might make cuts, so I wasn't interested.  Recently, Cinemax has had it frequently, and I thought that went with HBO, but it turned out I didn't have it.
So, quite a surprise to discover tonight that they will finally have it again tomorrow - all set for recording!!
