Recently we had a film called PREY with lions.
It wasn't that bad, especially since the predators were big cats; usually films with lions, tigers, or bears etc. are dissapointing, because the scenes with the animals look so clumsy. (It's not very wise to incite a tiger when his acting looks a little 'tame').
I also remember a film from the seventies (?) with lions that was quite frightening, maybe lions are better trainable than other large predators, I don't know (you see them more often in circusses too)
