Twilight Zone Marathon (Sci-Fi channel - US)
I don't know how many of you have noticed this but the annual 4th of July Twilight Zone Mararhon has started earlier than usual this year. As I'm writing this they have already been airing for a couple of hours.
But there is something new this year. The Sci-Fi channel has included the '80's version of the show with the classic (the classic episodes begin airing tommorrow) so if you haven't seen the versions from the 1980's now is a good chance to see them.
Accordong to Sci-fi channel's schedule the last episode that they will air will be at 5;30 AM on sunday morning - That's when the marathon stops.
(Don't forget that the station breaks with infomercials during the 6:00 to 8:00 (9:00 on saturday) time period).
