I expected that Jakks Pacific would hold the crown with a 20- or even 31-inch take on the Bounty Hunter we all love, but no - this was not to be.  It turns out that the Comic-Con debut of the  Star Wars Boba Fett Life-Size Vintage Kenner Action Figure (pre-order yours, if you dare) takes the cake at 6-feet tall.  Gentle Giant makes this figure to sell similarly sized Stormtrooper and Darth Vader action figures.  That's 72-inches of your Boba Fettish complete with red rocket, blue blaster, and a display stand.   Having seen one up close myself, I can tell you that it's the kind of thing any of us should be so lucky to have in our office.
