The Sci Fi Channel is airing three James Bond movies on Thanksgiving evening between 4 pm and 11:30 pm ET (with repeats of the last two movies immediately afterward). They are the first 3 Pierce Brosnan films: Goldeneye, Tomorrow Never Dies and The World Is Not Enough. Sometime during this "Bond movie marathon" (as the Sci Fi Channel describes it, although 3 movies is not really a movie marathon), Sci Fi will air a preview of Season 4.5 of BSG.
I don't know how long the preview will be. Maybe 30 seconds, maybe one minute. It could be interesting since I like Bond movies anyway. But I'm a little concerned that Sci Fi will air yet another big spoiler in a BSG preview. They've done it before, especially with the episode previews that air after each regular broadcast.
Anyway, it's up to you whether you want to risk seeing a major spoiler or not. But at least you have been warned. If you don't want to know about any major spoilers, avoid the Bond movies on Thursday. Otherwise, take a peek and see what intriguing scenes Sci Fi might show.
A reminder about spoilers: If Sci Fi does show a major spoiler, you can discuss it on this or another thread, but please use the "spoiler" tags to hide the info. Use square brackets around the word "spoiler" and be sure to include the closing tags with square brackets and a slash mark before the word "spoiler". If you're not sure it's a major spoiler, be safe and considerate of other visitors to the forum and use the spoiler tags. Thanks.
