I need Help With a Problem about movie times?

okay so im going with my friend to the premiere of Eclipse on tuesday night at cinema world at lincoln mall in lincoln RI. the time of the premiere is at 11:59 P.M. , And my friends mom said she cant go unless my dad is with us in the movie or in the thearter. So my dads girlfriend said shel go see a movie while where in our movie. The only problem is im not sure which movie they should go see because "get him to the greek" is at 10:30 and its the longest movie i could find & it ends at 12:30 and eclipse ends at 2:30 a.m. .... does anyone have any suggestions of what we can do to solve thiss problem? My dad was just going to drop us off at 8:30 p.m so we can get goood seats. and they where going to come back for their movie (which ever one they see). And we already bought the tickets so i really need help from anyone !!!!!!!!!!! thank you. (:
