Apparently, a 300 Sneak Peek aired during last night’s broadcast of “Heroes” and “Prison Break” but seeing as how I don’t watch “Prison Break” and “Heroes” is now airing at the same time as the Jack Bauer Power Hour, I missed it. If you’re like me, however, Warner Bros. has stepped in to save the day by providing us with delcious quicktime links to the TV spot. And just for good measure, they’ve thrown in a brand-spanking new poster. Links for the TV spot are as follows: Small, Medium, High, Super-High. 300 opens March 9th.
