From the "Special Features" menu of Disc Two, highlight "Leone's West" and press left to highlight a badge. From there, press down either once, twice, or thrice to highlight the Man with No Name's figure, a cart, and some coins, respectively. Clicking on any of these four icons will lead to a bonus interview segment with Eli Wallach; the exception is the figure icon, which leads to a Clint Eastwood interview. The interviews run about three minutes total.
