Use the farce, Luke: Mark Hamill is the prankster we need

Lucasfilm's month-long charity sweepstakes, Force for Change, is drawing to a close. And the Star Wars family is going to great lengths to make sure you enter.

There's a theme emerging in these videos: surprising Star Wars fans with their idols in the flesh is one of the most heartwarming and hilarious things you can imagine. (We know, you can imagine quite a bit.)

First we had John Boyega photobombing fans at a Star Wars Celebration photoshoot in Orlando last month. Now Mark Hamill steps in to play Candid Camera — and it's no surprise to find that such a role fits his personality perfectly.

The fact that Hamill's second most famous role after Luke Skywalker is The Joker, which he voiced in the Batman animated series, should give you a clue: Hamill loves to play the prankster.

(In fact, if there are any producers out there looking to revive Candid Camera, Hamill would make an excellent modern-day Allen Funt.)

He also genuinely loves the fans, a fact that became clear at Celebration. Hamill basically performed group therapy to combat his grief for Carrie Fisher, in a performance that was as intimate and off-the-cuff as it was moving.

And when two fans turned the tables and surprised him with a wedding proposal, the delight and joy on Hamill's face was brighter than a double sunset.
