Regarding Yojimbo, Wikipedia is your friend. Most know the name from the classic Akira Kurasawa film, Yojimbo, which inspired later films such as "For a Fistful of Dollars" with Clint Eastwood and "Last Man Standing" with Bruce Willis (both of them were practically 1:1 recreations, just in different settings, and both credited the Kurosawa screenplay). The sword work in Yojimbo is some of the best ever filmed.
