I can understand student films requiring non-paid actors, to help them get things right, as we have the experience of hanging around, because the daylight changed or things have to be moved around etc.
It is also a good thing for inexperienced actors, to get the experience of 90% waiting and 10% filming, with perhaps 24h of shooting equaling 1m of screen time.
But I agree, why do we bother, with having CV's etc, if nobody can be bothered reading the stuff. That's why they have casting-directors and producers. To separate the wheat from the chaff.
After that, we used to have to go for screen tests, to see if we fitted with the person we were to play opposite, let's say Toni Brooks and I had been shortlisted, and they wanted to see if we could deliver the chemistry based on the script, be it a love/hate relationship, murder most foul (albeit fowl if I killed her budgie), or whatever.
There are exceptions to the rule. I sent in a self-tape, and really rehearsed the scene to deliver good acting.
I got a response back, asking me for another self-tape, as they hadn't specified that they wanted me to be emotionless and speak in a monotonous robotic voice. - My son was stunned, as he couldn't understand why, but he shot me speaking like that, and then said: "That's just stupid". - Guess what. I landed the part.
