If you're looking for your first Bergman movie, run away from this one. Go watch Persona instead.
About the movie: it has a complicated start, plain boring. People talk too much instead of showing and in essence it's theatre being filmed and nothing else. Actors are doing theatre and it happens to be a camera nearby. It starts to get better by min. 30 and from there on it takes a way better turn, incorporating themes from Wild Strawberries and other of his known works.
This is a movie about dreams, however i feel Bergman didn't create a sufficiently effective mise-en-scène, with lots of hero shots and only quick glimpses at a scenery that had more room for development and details; it may have been because of budget as this was a TV film but i feel there was a lot of potential, camera movements, camera angles that were only partially incorporated bit by bit towards the end of the movie, but not embedded as a core element of it.
It baffles me that there's only one review for this film apart from this one so i invite anyone who read this to go watch it, if you like Bergman you won't regret it.
