This may not be possible due to access... but what you need to be able to do is apply more torque without crushing the can. And a good way to do that if there's room is to put TWO filter wrenches on the can- that way neither is so tight as to crush the filter, but you can apply twice the torque. I've used two strap-type wrenches, or a strap and a socket, a socket and pliers, etc. And I've never met one I couldn't remove, even on industrial diesel engines where the filter holds a gallon or more.
If access won't allow two wrenches, your best bet is a sturdy and tight-fitting socket-type wrench. The plastic ones are junk- the stamped metal filter sockets work much better. Also the one that ncguy suggested works well.
I would strongly advise that you DON'T drive a screwdriver through the filter. You need to avoid damaging the outer shell if at all possible. 'Cause if the can collapses and/or peels off (and both are common on badly stuck filters), then you have a much worse problem on your hands than what you have now.
If you absolutely can't get the thing loose... I'd take it to a dealership and pay for an oil change. Chances are that a guy who does this stuff all day will get that filter off with less trouble than you'd imagine. And you're more likely to avoid COMPLETE idiots if you go to the dealer rather than Jiffy-Lube.
