Re-watching the original Tron movie with some friends the other day in preparation for the theatrical release of Tron: Legacy, I was struck by several similarities between Tron and Star Wars: A New Hope (spoiler warning):

characters:
- that loveable rogue Kevin Flynn / Han Solo
- old master Dumont / Obi Wan Kenobi, each of whom has an Obi Wan moment
- Sark and Darth Vader are the Dragon in front of Big Bad MCP / Emperor Palpatine with the assistance of an army of anonymous Mooks who can be impersonated by dressing as the enemy
- Evil Brits: Tron's Dillinger/Sark, Star Wars' Emperor Palpatine and Grand Moff Tarkin
Tron lines and light sabers embody both Good Colors Evil Colors and Power Glows
"Thank the Maker!"
IIRC, during their battle Sark invites Tron to join him; I don't remember whether the implication was We Can Rule Together à la Star Wars or You Will Be Assimilated
a short sneaking-on-a-ledge scene in Tron (anyone remember the details?) reminded me of Obi Wan's edging his way along a ledge in the Death Star's power generator trench
shots of the massive Battle Star (Sark's carrier | a Star Destroyer) moving through space parallel to the viewer's line of sight
would it be a stretch to call the sort of seedy-looking in-game neighborhood (with requisite shady humanoid aliens) we briefly see in Tron a Wretched Hive?
battle squadron call signs: Blue Leader, Gold-1, Gold-2, Gold-3 on light cycles; Gold Leader, Gold-2, Gold-5 in Y-Wings; Red Leader, Red-2, Red-3, Red-5 in X-Wings
some of the sound tracks, particularly the flute sections, sounded similar to me
Flynn gives a Big No when Sark orders him to finish off Crom; Luke gives one when Darth Vader kills Obi Wan
Tron's Duel to the Death with an energy weapon is with discs; in Star Wars they do it with light sabers
outside the films themselves, they share stab-the-sky posters and, some argue, awards snubs
