A photo of a lion strapped onto a machine in order to make the iconic MGM intro of a lion roaring is actually a photo of a lion being diagnosed at the vet's office. Luckily, the lion made a wonderful recovery and is now completely healthy. Also, an interesting fact is that there have been 7 lions that were used to create the MGM intro, the current one, who's name is Leo, has appeared in most of the movies since 1957.
