Bess Armstrong riding real killer whale

She did train for that. There's a making-of documentary that shows her practicing it. She is also interviewed explaining it took time for her to accomplish. She also mentions having to allow the whale to trust her before it would allow her to ride on it's back.

Wow, that must have been a great experience for her.

Poor whale

Wow, a lot of trouble to go through for a rather piss poor movie.

I wonder how the actors trained for that final scene when the water crashed through the control room…in 3D.

Greatest moment in cinematic history.
