Tonight I wanted to watch Godzilla on HBO. It started at 7:00, but I was 15 minutes late. I can't find any way to watch the movie from the beginning. The "Watch Options" only lists "Watch on HBO" but no option to restart from the beginning or watch On Demand.
So, the only option seems to be to wait until it's finished airing on HBO and then try to watch it On Demand, or wait for the second airing on HBO later tonight. That doesn't sound right. Is there really no way to watch from the beginning while the movie is currently airing?
I think I may have answered my own question...
I tested this with movies airing on other channels (Cinemax, Showtime, Starz) and I was able to use the "Restart" option on all of them to start whatever movie was currently airing from the beginning On Demand. So, what was different about HBO? I think Godzilla might have been a premiere tonight, so maybe it's not available On Demand until after the first airing?
Anyway, now that it's done airing on HBO I am able to watch it On Demand.
