Tarantino's foot fetish is actually a deconstruction of the human condition of having feet.
In Pulp Fiction, John Travolta plays a guy called Vincent Vega. In Reservoir Dogs, most of the characters are known only by their code names -- except Mr. Blonde (Michael Madsen), who happens to be called Vic Vega. Coincidence? Nope, Tarantino has confirmed that they are brothers, and at one point he even considered doing a prequel about the two before they died in their respective movies (though he says it's unlikely now because of the actors' ages).
The amount of CGI needed would bankrupt many studios.
That's just the tip of the iceberg, though. As you might recall, Tarantino's movie Inglourious Basterds ends with the slightly unrealistic scene where Hitler is gunned to shit by a group of Nazi-hunting American Jews in 1944, rather than killing himself in his bunker the following year. If you ever wondered what the world would be like if World War II had really ended that way -- well, it turns out Tarantino has been showing us that reality for the past 20 years.
