Because time no longer has meaning and this disease-ridden temporal vortex has enslaved us all, you may be curious to hear that 1980's The Empire Strikes Back, an indie film that we do hope you someday make some time to go see, has returned to drive-ins and something we think we have once heard of called "movie thee eighters."   According to Deadline it's on track to add another $400,000 to $500,000 to its domestic tally this weekend thanks to a generous lack of alternatives.   It made $175,000 just on Friday!
