It's been awhile since I've seen trailers for the PT and OT, but today I did during Futurama on Sky One. On May the 4th-6th, movie channel Sky Showcase (channel 303) will be showing the six films. Times: TPM - (May 4) - 6am, 8:30 pm, (May 5) - 6:15am, 8:15 pm AOTC - (May 4) - 8:30 am, 11pm (May 5) - 8:35am, 10:35 pm RoTS - (May 4) - 11am, (May 5) - 1:30 am, 11am, (May 6) - 1:05 am ANH - (May 4) - 1:30 pm, (May 5) 4am, 1:25 pm, (May 6) - 3:35 am ESB - May 4) - 3:45 pm, (May 5) - 3:40 pm RoTJ - (May 4) - 6pm, (May 5) - 5:50 pm Not sure if it continues after these times as the Sky program guide ends at that point. The channel is also available in HD. Edit - and that's a wrap from the Sky Guide. If I have insomnia those nights I know where to head..
The trailer was great, saw it on Tuesday. A whole channel dedicated to Star Wars....this is definitely the year of the force. EDIT: Added video of the marathon
That's a longer version of the trailer I've been seeing. There are some added scenes. I think my one has been around 30 or 45 seconds.
