Open Cinema is a small cinema for 64 spectators, originally built in the town of Guimarães, Portugal, as a temporary structure. Architect Colin Fournier and artist Marysia Lewandowska were commissioned to make a film and build a public cinema for the city's 2012 European Cultural Capital celebrations. This brief led to the creation of a new form of cinematic experience, in which spectators were immersed in the 'black box' of cinematic illusion from the waist up, while their lower bodies remained grounded in a public square. Open Cinema was conceived as a tribute to the politically radical cinema culture championed by Guimarães' local film club as well as to the town's manufacturing past.

Open Cinema was free to the public, encouraging social participation and offering unusual cinematic experiences to those who were willing to enter this cinema suspended between the imaginary and the real. The cinema screened a loop of 23 film trailers from the CineClube de Guimarães archive, each about three minutes long. The trailers were chosen by the employees of two local factories, who voted for their favourites at screening sessions held during lunch breaks.

The pavilion has also been realized at the 2013 Lisbon Architecture Triennale.
