John Ritter's Lynchpin Performance

"Hero at Large" is a very rare thing indeed. It features what I call a "Lynchpin Performance," in that one actor (in this case John Ritter) is carrying the bulk of the film on his own and that if you attempted to cast anyone else in that role, the whole thing would have fallen apart!

So, no. I don't think a remake is possible. More about it is on my review here:
