Blackfish Trailer – Inside the world of theme park killer whales

There’s been an increasing feeling among some that it’s not right to keep killer whales in captivity. After all, they can grow 25ft long, live in comparatively small pools and are very smart. That’s what the documentary Blackfish looks at, suggesting that perhaps the way these animals are kept literally causes a sort of psychosis.

It concentrates on the story of Tilikum, who was caught in the wild in 1983, and since then has been involved in the death of three people, most famously SeaWorld trainer Dawn Brancheau, who was killed in front on spectators when the animal dragged her into the pool.

It certainly doesn’t look like Blackfish is going to pull any punches in savaging what it sees as a cruel industry.
