While learning about my Marvel crushes I learned that Jeremy Renner was on CSI for a short time and i'm curious to know if it was his first ever TV role? I know he debuted in his very first movie National Lampoon's Senior Trip and did commercials. What season of CSI did Jeremy Renner debut in and what character did he play on CSI? If Jeremy Renner was in CSI I would adore seeing his episodes just to see Hawkeye act and be cute
