So while this is happening, two women (credited as The Blonde and The Brunette, Jane Birkin and Gillian Hills respectively) keep wanting them to help them by taking pictures or something. He gets mad at them. And, while this is happening, he is assembling a book of pictures of the factory workers and of the couple with this guy named Ron (Peter Bowles). In the last 30 minutes, it seems like it is building up to a climax, but no. Thomas goes to a strange Yardbirds concert where Keith Reif is lip-synching to himself, and there is no Eric Clapton to be seen. I guess the "highlight" of the scene is when the bassist (I'm not a hardcore fan of the Yardbirds) smashes his bass and Thomas keeps the neck and then throws it out while walking on the street. The scene has no relevance to the movie. Maybe Antonioni felt obliged to add some random pop culture into the movie. I don't know, but it really doesn't help the movie's cause.
Then, Thomas goes to Ron's party where people are rolling joints and just chilling. He then realizes that he must take a picture of the body. He didn't take the chance the night before when he saw the body. But when he goes, the body is gone, and he is just standing around watching mimes play air tennis. Not very fulfilling.So the lesson here is you don't mix art and 60's pop culture together. I mean, the movie was good up until the last 30 minutes. I won't talk about the acting, because it is not important. The movie is beautiful and is extremely artistic and symbolic, but the greatness is broken by the "needs" of the times. It's the same thing I always grimace about when I go to pop cinema: directors try to be hip and impressive, instead of just creating something halfway artistic, and wind up coming out embarrassing. I didn't find Blowup embarrassing, but I wonder what would have happened if Antonioni had not tried to be more hip than the movie needed to be. B+
