Film Crew Wants to Shoot My Bees

I received a request for a film crew to come and briefly shoot some footage of my bees for a TV movie. They want to have a couple who give away honey as favors at their wedding look at the hives. I would have the people on my property for about an hour one morning. I guess I would have a frame with honey ready for them to taste after they film the bees. They have a contract that I would have to sign, but I am still worried a little about the liability. If anyone gets stung, then I might be responsible.

The positive side would be that the girls would be on television. There might be a location fee, too, although I doubt it would be very much.
