Eventually, Martinez' interests shifted and he focused his attention toward film scoring. A tape Martinez had put together using new technologies made its rounds, leading him to score an episode of Pee-Wee's Playhouse. The same recording also ended up in Steven Soderbergh's hands and Martinez was hired to score the famed director's first theatrical release, 1989's sex, lies, and videotape. Martinez's longstanding relationship with Soderbergh has continued through the years and they have worked together on ten theatrical releases including Kafka, The Limey, Traffic, Solaris and 2011's Contagion, as well the Cinemax series The Knick.
