Movie still from 'The Campaign'

ST. LOUIS (AP) — Comedian Will Ferrell is celebrating his birthday in St. Louis.

Well, almost.

Ferrell and fellow comedian Zach Galifianakis are scheduled to be in St. Louis Tuesday for a so-called whistle stop campaign to promote their new movie "The Campaign." The appearance comes a day after Ferrell turned 45.

Mayor Francis Slay proclaimed Tuesday "Will and Zach Day" in St. Louis.
