Night Tide (1961) review

On shore leave and out to get lucky, sailor Johnny (Dennis Hopper) hits on a young lady he meets in a bar named Mora (Linda Lawson) - who "plays" a mermaid at the carnival - but gets warnings about her being dangerous since her last two boyfriends died.  For being something of a "mystery" film, it's very unengaging and stiff, and it's not helped much by Hopper and his ten thousand yard stare (how easy was it to score grass in the early 60's?).  You know something's not right when even an attempted murder - while SCUBA diving! - fails to provide any kind of excitement.
