Out of the beaches and into the boudoirs go Frankie Avalon, Annette Funicello and the rest of the gang in Pajama Party. Actually, the whole megillah is as innocent as a newborn babe, but there's plenty of smirking and snickering during a wild 'n' wacky girl's slumber party. Frankie Avalon has only a cameo, relinquishing center stage to Tommy Kirk, playing a teenaged Martian (!) studying the lovemaking rituals of Earthlings. Old-timers Buster Keaton, Dorothy Lamour and Elsa Lanchester also weave in and out of the proceedings, with Keaton the only one who doesn't look as though he wishes he were somewhere else. And of course there's good old Harvey Lembeck as good old Eric "Why Me?" Von Zipper. Director Don Weis took over for Beach Party's William Asher in Pajama Party, remaining in charge for the ill-fated sequel Ghost in the Invisible Bikini (1966).
