If you are an actor and are approached by someone who says that they are a producer, (or agent/manager for that matter) ALWAYS be skeptical. Here's what you should do:
1. Get their name and contact info.
-Then do your research. Find out as MUCH as you can about the producer to see what this person has actually accomplished in the industry. IMDB is a great starting point as well as BackStage.com.
2. Talk to everyone that you know about this person before getting involved/signing contracts, etc.
--There have been stories where "fake" producers have scammed, even committed crimes against actresses and actors because they tell them that they promise to make them a star..blah blah blah.
3. NEVER meet with a "producer" (or anyone for that matter) unless it's at a public place
---such as an office, a restaurant, etc. You have to assume that this person is NOT legitimate until you can see that they are. Perfect example is a horrible crime that occurred in 2003 regarding an actress who fell victim to this type of scenario of being lured by a phony "producer" psycho. You can read about that here, (warning: it is a graphic story. Click Here for story)
My point is that you must ALWAYS be careful- (in Hollywood and everywhere else!)
Hollywood is a whacked-out place and there's a lot of weirdos who are scam artists and will try and manipulate you. Obviously the above story is not one that happens everyday. HOWEVER there are soooo many fake wana-be producer/manager/agent people, that you can never let your guard down.
