'Step Brothers' Film -- Catalina Wine Mixer Going Down ... For Real

The Catalina Wine Mixer – the legendary scene from Will Ferrell's "Step Brothers" flick – is coming to life, and it's going to be just like the movie, right down to a helicopter landing.

The film company has given a Santa Catalina Island business the green light to recreate the scene in glorious detail for the event, which kicks off next week.

Just like the movie, The Dan Band is headlining, but the sweetest part ... they're planning on landing a helicopter on the lawn of the event, just like the movie finale!

No word if Ferrell or John C. Reilly will encore their “Por Ti Volare” and “Boats 'N Hoes” mash-up.
