Cinematic Titanic is coming to San Francisco's Marines Memorial Theatre on Friday and Saturday, February 13 and 14.
Their website says to use the code "MST3K," but that is of no use at this point. The code provides no discount on the price of the tickets. It was a presale code that is now meaningless, since the tickets are currently available to the general public.
