well, you could look at the divide between binford's 'new Archaeology' vs post processualism
Geographic Information Systems (GIS) vs heuristic studies ie phenomenology (Chris Tilley)
maybe american field method vs european ones ie the checker board vs the trench
evolutionary archaeology and the role of agent based simulation
im not too hot on North american current debates but these are the current european/british ones
the role of the media in archaeology/public archaeology - how archaeologists are always the villan(grave robber/tomb raider) they cause problems - Carter and the Tutancarmoon - the curse of the mummy.
films / tv
-Indiana Jones
-Tomb Raider
-Dr Who (BBC 2006/5) - an archaeologist decifered some markings and called forth the devil!
-the Mummy
-on sky loosely Bones (sorry watching it at the mo and they are about to do a very rapid GPR survey and they are using metal detectors - it took them 30 seconds and some very dodgey camera work lol )
also Channel 4's Time Team (British)
I agree with 'bush saves...' as in the two approaches between american and european methodologies in particular you could look at Ian Hodder, whom after his employment at an american univeristy split the department in two! due to the opposing viewpoints!
if you want any bibliographic references i can try and provide you with some, these topics are a bit biased as im doing a masters at University College London in GIS - and its all ive got on my mind.
Good luck
