First and foremost...
THERE ARE NO RESORT BUSES THAT RUN OUT OF THE TRANSPORTATION AND TICKET CENTER. The only exception to that would be for Fort Wilderness and Wilderness Lodge.
Bus transportation will generally continue to run from the Magic Kingdom 90 minutes after it closes. Same with Epcot. So you can catch the monorail to either location, and then catch the bus to All-Star Movies from there.
Worst case, you could always use Downtown Disney as the transfer point.
