Michael Crawford, Captain Toy, has posted a great review of the Mars Attacks! Martians from Hot Toys on his site, MWCToys.com. From the 1996 movie Mars Attacks!, the Martian Soldier and Martian Ambassador figures are 1:6 scale, standing about 10-inches tall. With over 13 points of articulation, the poseable figures include several additional accessories and extras, including weapon, interchangeable hands, display stand, and more. Each retails for about $120.
