Rescue Me alum Larenz Tate has been upped to series regular on USA’s original medical drama series Rush, set to premiere July 17. From writer-director Jonathan Levine and Fox 21, Rush follows Dr. William Rush (Tom Ellis), a “medical fixer” who privately caters to LA’s elite. Tate plays Dr. Alex Thomas, Rush’s best friend dating back to medical school and one of the few constants in his life. Unlike Rush, Alex is a man with a plan — he works as a high-ranking physician at one of Los Angeles’ top hospitals and appears to have the ideal family life that Rush has long resisted. Tate played the role in the pilot as a guest star as he was in second position to comedy pilot Mr. Robinson at USA sibling NBC. Mr. Robinson has since been picked up to series but Tate won’t continue on the series, instead taking on full-time duties on Rush. Tate, repped by Paradigm and Brillstein’s Jai Khanna, recently recurred on Showtime’s House Of Lies.
