Police Academy at its core is a harmless, innocent poke at authority that does find a fresh background in a police academy. Women in the film, such as Kim Cattrall as an Ivy League-type and Leslie Easterbrook as a busty sergeant, have almost nothing to do. Marion Ramsey as a timid-voiced trainee is fine in the film’s most vivid female part.Co-writer Hugh Wilson, makes his feature film debut as director, and his scenes are short and fragmentary. He gets a fresh comic performance from Michael Winslow as a walking human sound effects system (the film’s most appealing turn). Through it all, Steve Guttenberg is a likeable rogue in a role that’s too unflappable to set off any sparks.
