A Desperate Housewives and The Event actor is coming to CSI.

Roger Bart has landed a colorful guest-starring role on the CBS crime drama, playing an eccentric wig maker. Bart’s character makes wigs for women suffering from cancer and has a very high opinion of the artistry of his work — “giving back what God has taken away” and all. He’ll appear in an episode during the February sweeps.

Meanwhile, today marks a CSI milestone: After 11 years, it’s Marg Helgenberger’s last day of filming on the crime drama.
