Colin Farrell: I'm Backing Leonardo DiCaprio for an Oscar ... and Soccer in America

Add Colin Farrell to the growing list of people who think this could finally be Leonardo Dicaprio's year to win an Oscar.

We got Colin arriving at LAX Sunday night and he had high praise for Leo's performance in "The Revenant" -- making it clear there's more bromance between the actors than rivalry.

As a bonus ... the Irish native also shed some light on why football (soccer) is so popular in his homeland and still struggling in the States. We also love his New Year's resolution!
