Made for TV movie about group that sails to prehistoric island encounter seven gill sharks and killer ostriches. Appeared 1967-1969. Title? Network?
I’m taking a guess because I saw this movie on YouTube some time ago and it has some nasty ostriches and sharks. It is from 1967, but unfortunately I do not know when it was on tv.
Please take a look and see if this is the one. https://en.m.wikipedia.org/wiki/Island_of_the_Lost
