nifty little episode play mainly for laugh and but with clever dollop of suspense . somehow a martian have sneak aboard a broken down bus on it way to nowhere and but which passenger be it and ( talk about your illegal immigrant . ) . all star support cast and from wild eye jack elam ( ham it up shamelessly ) and to sexy jean willes ( if she the martian and then i say let open the border . ) and to cruel face john hoyt ( the most obvious suspect ) and along with familiar face john archer and barney phillips ( and a nice turn from bill kendis a the bus driver ) . make for a very entertaining half hour even if the action be confine to a single set .
