‘spiderman21′ says you might be able to check out Elektra a bit earlier than Friday:
I just watched Adult Swim last night on Cartoon Network and they had an advertisment for a sneak peek for Elektra at Midnight Thursday. Hope this helps.
UPDATE: ‘chopstyx’ says Cartoon Network is talking about a segment on the movie on the actual channel:
The Elektra sneak peek spiderman21 refered to is not a midnight showing at theaters, but a ‘sneak peek’ on Cartoon’s Network Adult Swim sometime Thursday night. Tune in to the channel to see it!
