When Frogs came out, it had some critics reaching for their superlatives to compare George McCowans directing debut with that of George Romero in Night of the Living Dead (1968). This was almost certainly overstating the case, especially in terms of McCowans subsequent films (see below). There is the odd effective moment. Most of this rests in Mario Tosis sparkling natural photography all light shimmering off water, shafting down through trees and the excellent animal scenes.
However, the script leaves too much to be desired. Proceedings are too episodic, only centring around the interminable dispatches of the victims who are so one-dimensionally crafted they are frequently difficult to tell one from another. The film seems to have no purpose other than to set them and the animals up to kill them off. Ray Millands patriarch starts out interestingly as the only one who seems to have any control of the situation but degenerates into simply being a stubborn old idiot, which is pointless as he is never given any reason for so obsessively wanting to stay on the island and is painted far too cynical to do so for purely sentimental reasons.
Canadian director George McCowan went onto direct a couple of other dreary genre entries Shadow of the Hawk (1976) about duelling Native American sorcerers and The Shape of Things to Come (1979), one of the worst films seeking to exploit the late 1970s science-fiction boom, as well as the earlier tv movie The Love War (1970) about aliens warring on Earth. He spent most of his career working in US television.
