The person mentioned that they later revealed themselves to be SAG and wanted the company to pay them wages for what they had already done. I'm not sure how much of it was myth vs. reality, but I won't be signing any contracts with SAG, so I guess we'll move forward and let him play the role.
It's simple. You audition them. In Los Angeles there's PLENTY of good non-union actors. I don't know where you are doing your casting. There's droves and droves of people in LA who want to come in to audition. Never had a problem with finding talented non-union actors. And on the flip side there's also a lot of SAG actors who can't act their way out of a wet paper bag! Of course their goal is to join the union. So what??? Have them sign a deal memo. Simple. Of course you have backup actors if they flake out the last minute. 1 out of 10 actors flake out at some point before your shoot. Just have backup choices.Wow...the only reason you would use a sag actor is for box office draw? Come on? Really? If you're hiring non union actors you are hiring (on average) amateurs. Sure there are a handful of amateurs that get into the union early, but they usually pay dearly when they don't have a resume to back having union status. If you're hiring an actor that isn't union...you're hiring an actor who is doing whatever they can to become union. So even the good non union ones are doing whatever they can to get in.
Yes you can find good non union actors...but that actor's goal is to join the union because that is the only way to make a living as a working actor. Word of warning...if a union job comes along out of nowhere in the middle of your non union shoot...do you think your non union guy wouldn't jump at the chance to go do that other tv one liner? Its not professional but I've seen it happen because they want that card.
With more experience that actor will become union. If you're hiring 20 non union actors for your film...how many are going to be good actors? How many of them will have worked on set? Hell how many will be passable? I'm not saying its not possible...but you get what you pay for.
How often do you go on ebay and get an almost too good to be true deal? Once in a while, right? Same goes here...if you're not hiring pros...once in a while you can grab some great finds...otherwise you're praying that you can edit out anything that isn't great...
