This is an good movie to show as an anatomy lesson. They made a few gaffes, but by and large, stuff is accurate. And I will admit that for the 60s, the special effects are phenomenal. But the plot drags (especially the beginning--how long can you watch something shrink?) and has holes, and the acting is horrible. Raquel Welch's character Cora has three basic tasks: to stand around looking pretty, to occasionally hand something to her boss, and to every once in a while do something that requires her to scream "Help! Somebody please help!" Still, I suppose that's more tasks than the other characters. Grant just stares at the camera in a grim and determind way, Dr. Duval recites inspirational quotes like he's reading them off a calendar positioned outside the window, and Dr. Michaels sits around being bald and muttering darkly in an accent.
