The Olympiad was written as a bad death metal band. Since no songs or lyrics were written for the band, Phillip Rainford was directed to base his singing on Eddie Vedder of Pearl Jam.
The band Hit Machine is shown playing "Love Remains" by leader Bart Hafeman in the movie. The band is actually playing 'Dynamite' by Taio Cruz. "Love Remains" was chosen as the song in post-production.
The winery sequence was originally written as a house party. Edith Gidley suggested it be changed to a winery. David Hill Winery in Forest Grove, Oregon was originally secured. Changes in the production schedule forced a change to Plum Hill Winery (as seen in the film).
