Eli Wallach was 50 in when this was made? Wow!

This really blew my mind, especially seeing as how people aged a lot rougher in the era in which this movie was made; he could have easily passed as being in late 30s here. The fact that Van Cleef was a decade younger than Wallach also blew my mind, Van Cleef was only 40 here yet he looked like he was older than Wallach
