Zeta One (1969)

Starring James Robertson Justice, Charles Hawtrey, Robin Hawdon, Anna Gael, Brigitte Skay
Directed by Michael Cort
(actor & director credits courtesy IMDB.com)

A secret agent becomes involved in a mission to trace a young woman kidnapped by a race of beautiful women from outer space.

This picture is one of the most misogynistic movies I've ever seen, featuring rampant female nudity, and distasteful torture scenes involving the female characters.  Obviously intended to titillate the male audience, it starts off rather successfully in that department, but there's no inventiveness in the story or staging to sustain the patience of even a viewer looking for cheap thrills over the course of the film.  Hawdon is a charming enough lead and Yutte Stensgaard makes a memorable impact in the film's framing sequences, which makes it a little more perplexing while she's not in more of the film.  The filmmakers also waste opportunities to take advantage of the sci-fi setting, making for a pedestrian film hoping to hold the audience's interest with little more than the lovely ladies it disrobes.

Carry On Screaming! (1966)

Starring Harry H. Corbett, Kenneth Williams, Jim Dale, Charles Hawtrey, Fenella Fielding
Directed by Gerald Thomas

A police detective tries to solve a series of disappearances of young women, and follows the clues to a mad scientist who's been using a werewolf lackey to abduct the women.

Part of the long-running British "Carry On" series of movies, featuring a recurring cast of character actors in a comedic spin on a popular movie setting each picture, this entry targets horror films, and although not the funniest outing in the series, it's still charming, with a few jokes that stick.  Williams is particularly good as aptly-named scientist Dr. Watt, who uses electricity to recharge his dead body, but is still concerned with maintaining proper decorum.  Although the story is completely silly, Williams and the rest of the quality cast treat it as seriously as possible, making for good fun.

The Terrornauts (1967)

Starring Simon Oates, Zena Marshall, Charles Hawtrey, Patricia Hayes, Stanley Meadows
Directed by Montgomery Tully
(actor & director credits courtesy IMDB.com)

Scientists listening for signals from outer space detect one and transmit back, resulting in their being transported to an asteroid by an alien spacecraft.

Although the premise of this film, based on a novel by Murray Leinster, makes for an interesting sci-fi adventure, this is compromised somewhat by extremely low-tech special effects, and yet I still had a good time watching this.  It's regrettable that outdoor landscapes for an archaeological site on Earth and an alien world look a bit too similar, and a rescue sequence involving hostile aliens is a bit too brief.  However, the cast of colorful characters, a pretty good music score, and some mystery as the scientists try to figure out alien contraptions all add up to an entertaining movie.
