When was the last time you saw a movie that didn’t feature some kind of credits in the beginning as well as at the end? I’m willing to bet that you’ve never seen even one such film, unless we’re talking about obscure YouTube releases here.
Now, why is all this text necessary? Not only is it totally superfluos information for the overwhelming majority of the viewers who just want to watch the movie; even if people actually were interested in this information, why would you have to put it in the actual movie and not somewhere else, for example at a dedicated webpage?
Including text that reminds your viewers of the fact that they actually are watching a movie is not only a bad idea if you’re trying to create an enthralling experience for them, it’s also aesthetically questionable since it mixes up the real world with the film world. Would you have a speaker read a list of all the people involved in the making of a musical album on one of the tracks? (For the record, I don’t really like the practice where artists put their signature on their paintings either.)
I’d love to see a movie that cuts out all the excessive crap. Just show me the movie. Nothing else.
