It's a matchup of heavyweights, as Moviefone's Will Ferrell Tournament advances to the Final Four.

After two rounds of voting, the four No. 1 seeds -- Buddy the Elf ("Elf"), Ricky Bobby ("Talladega Nights"), Frank the Tank ("Old School") and Ron Burgundy ("Anchorman") -- have all made it to the semi-finals, where they'll face off in a battle of wits (and, in Frank's case, heavy drinking).

(For those who haven't been following, the tourney is in honor of "Casa de Mi Padre," Will's latest film, and the NCAA Men's Basketball Tournament.)

Now, you'll have until Monday, 3/26 at 12 p.m. to make your Final Four picks! (You can see the full updated bracket, with winners from previous rounds, below.)

UPDATE: POLLING NOW CLOSED
Advancing to the championship game are Ron Burgundy ("Anchorman") and Buddy ("Elf"). For the previous rounds voting results, HEAD HERE.
