One Tree Hill (2003-2012) is a teen drama / soap opera TV series created by Mark Schwahn, that aired on The WB and The CW network, for 9 seasons (187 episodes).
One Tree Hill is set in the fictional town of Tree Hill in North Carolina and originally follows the lives of two half-brothers, Lucas Scott (Chad Michael Murray) and Nathan Scott (James Lafferty), who compete for positions on their school’s basketball team. Their relationship evolves from heartless enemies to caring brothers as the show progresses, and the drama that ensues from the brothers’ romances with female characters including Peyton Sawyer (Hilarie Burton), Haley James (Bethany Joy Lenz), and Brooke Davis (Sophia Bush).
In an attempt to improve Life Unexpected‘s ratings by attracting One Tree Hill viewers, The CW aired a crossover event involving both shows on October 12, 2010. Beginning with One Tree Hill installment Nobody Taught Us to Quit, Haley James Scott (Bethany Joy Galeotti) and Mia Catalano (Kate Voegele) traveled to Portland (where Life Unexpected is set) to perform at the Sugar Magnolia Music Festival hosted by K-100. Haley and Cate Cassidy (Shiri Appleby) meet in the crossover and are “surprised to learn that they share a similar back story [as] mothers”. Music Faced, the Life Unexpected episode of the crossover, also featured Sarah McLachlan, Ben Lee, and Rain Perry, whose song Beautiful Tree serves as the series’ opening theme.
As usual, there is no DVD box set yet for the U.S. viewers (October 2014), but the complete One Tree Hill TV series on DVD is available since 2012 on Amazon UK, with English subtitles for all seasons (£55):
