(CNN) -- On this month's edition of The Screening Room we visit London's quirkiest cinematic venues, offering film-buffs an alternative to the multiplex.
The Secret Cinema transforms derelict theatres and empty warehouses into interactive worlds based on a mystery movie, unknown to the audience until the opening credits.
For those who like it retro, The Starlite Urban Drive-In offers a chance to re-watch classics like "Grease" from the comfort of an open-top car, provided and pre-parked for the audience's viewing pleasure.
Meanwhile, the Portobello Pop-Up cinema - located in a graffiti-covered train underpass - is quickly becoming a favorite hangout for the city's bohemian crowd.
Are these eccentric movie theatres merely a fad or an indication of where cinema is headed?
Plus, we speak to masters of laughter Edgar Wright and Jay Roach responsible for two of the year's most outrageous comedies -- "Scott Pilgrim vs. The World" and "Dinner for Schmucks."
