In the stuffed apartment of a nerdy professor - books, piles of papers, late romanticism murals of wounded knights and bereaved maidens. He only lives for his science, does not have a social life. Until he finds a hole in a wall. He peeks through and discovers a new world. In the next door apartment - fully decorated in day-glo painted furniture and pop art - young Londoners are fully embracing the swinging lifestyle: photographers, models, musicians. Parties take place, wild music is played and boys and girls experience life. By and by the professor gets sucked into this new world next door.
Even though there are some scenes that could be shorter, the director takes the time to let us know, how slowly but inevitably the professor opens up.
I love movies like Blow Up, Magical Mystery Tour, The Magic Christian, Performance, ...
This movie is not one of the cult films but has its own zeitgeist charme. It inspired Oasis to do a song with the same title. George Harrison did the soundtrack.
