Bio from NBC's Crossing Jordan Page

To Miguel Ferrer, the best part about playing forensic examiner Dr. Garret Macy in the NBC hit drama “Crossing Jordan” is that Macy is a complex man who still manages to maintain a reasonable degree of normalcy.
In contrast, Ferrer’s distinctive on-screen presence has often led him to be cast in somewhat offbeat character roles. He first attracted audience attention with a breakout performance in “Robocop.” He won critical acclaim for his portrayal of an FBI forensic expert – very different from Garret Macy – in David Lynch’s cult hit TV series “Twin Peaks.” In 2000, he delivered a stand-out big-screen performance as a drug dealer-turned-reluctant-informer in Steven Soderbergh’s Oscar-winning film “Traffic.”
Despite an impeccable Hollywood pedigree – he is the son of movie star Jose Ferrer and singer Rosemary Clooney – Ferrer initially began carving his career path as a studio musician (his credits include playing drums on Keith Moon’s “Two Sides of the Moon”). Bandmate Billy Mumy (Will Robinson on the TV classic “Lost in Space”) cast him in his first role in the TV series “Sunshine.” It wasn’t much of a stretch – Ferrer played a drummer – but Mumy had to talk him into doing it.
Since then, he has starred in the hardball detective comedy “Where’s Marlowe?” and in the thriller “Harvest,” where he met Leilani Sarrelle, then his co-star and now his wife. He lent his voice to Disney’s “Mulan,” and appeared in the Emmy Award-winning Stephen King miniseries “The Stand,” starred in the comedy series “Lateline” and the miniseries “Drug Wars: The Camarena Story” and guest-starred in the pilot of NBC’s “ER.”
Ferrer still finds time to play club dates with Mumy. Their band, the Jenerators, has released two CDs. Ferrer and Mumy also collaborated on Dark Horse Comics’ “Trypto, the Acid Dog” and “The Comet Man” for Marvel Comics.
In his spare time, Ferrer loves to play golf and ski and every year helps organize a golf tournament fundraiser for the UCLA Children’s Hospital. He and his wife and their two sons live in Los Angeles. His birthday is February 7.

Another triva tidbit that they left out is that his cousin is former ER star (and Golden Globe winner for 2000's O Brother Where Art Thou?) George Clooney.
