I've made a realization today having watched the two movies in rapid succession and I do suggest you do the same.
There are remarkable similarities between Mel Stuart's Willy Wonk and Andrei Tarkovsky's Stalker, go ahead laugh I know you wish to, but then consider it.
There are shots that are one to one, techniques similar the plot itself is heavily similar, and both have a similar relationship to the novel they are based on.
