Of all the director tributes I have seen, those by Joel Walden stand out as the best and most creative. This Canadian guy, 2 years older than me, truly has talent- he doesn't put together scenes from different films in a random way, but everything has meaning and significance, matches the music well, and combines beautifully.
The best one so far is "Martin Scorsese- The Works":
Some other excellent tributes:
I wouldn't be surprised if in a next few years seeing him make some films, and in some decades at most, seeing him receive some important awards.
