It is a good dot com name with exact keyword match for organic search, so I think you could get the figure you want but you may have to sit on it for some years, especially considering that most actors are currently out of work.
As @lock pointed out above, 'actors equity is a thing' so perhaps they are your enduser.
If it was my domain, I would develop it by listing actors insurance companies and information - perhaps even include a moderated forum. This will get it indexed in search and get some traffic coming in. You will then have a better chance of getting a good price based on real traffic.
