Need help finding an obscure movie?

Help please, have this movie on my mind. It may be Canadian, British, or american. OK hope my memory serves me well. this story is about this delivery guy who picks up a stranded woman on the side of the road. no, not a slasher film. He delivers the package to a "mad scientist" this scientist can now open portals to another dimension. the thing looks like a one man star trek transporter anyway there is an "accident" the scientist, then the girl then the guy in that order. when the guy falls through it's been two months since the scientist first fell in. The guy meet these suppressed refugees, some look human some look like blue star trek aliens minus antenna. this particular blue skinned dude uses red glowing orbs that comes from a vine that get hot and are used to start camp fires. one of the group is a small time thief and he likes the guy's watch, when the alarm goes off he tell the thief that it let's him know there is a thief near by. (as a joke.) OK back to the plot seams straight forward: guy goes though portal, finds damsel living in ragtag group dominated by warlord who then kidnaps damsel. He leads group of would be rescuers to warlord's lair to find the scientist working for the warlord. the 3 race back to where they showed up at. they vanish back to the real world leaving the thief alone. he was promised the watch by the guy so he says, Hey what about the watch? I don't know the name and it could be some what classified as sci fi Fantasy. i saw it on cable between 81 and 85 i guess. it could have been 70's ish too. any help would be grateful.
