The replies in here are interesting, and not in the least bit surprising.
You can find ways to paranoia about how your woman is interacting with men in most vocations, so I don't think that's a reasonable enough excuse not to trust a woman just because of her line of work (of course, there are exceptions before someone quotes me and mentions porn). The only true obstacle I see, personally, is not having enough time and energy for building a relationship, but if we could come to an understanding to make it work, than yes, I could commit.
The whole she's an actor and could be acting can happen with any woman. People in relationships act all the time and neither party knows any different.
