Sources confirm to me exclusively that Trauma actress Anastasia Griffith is joining the cast of Royal Pains in the major recurring role of Dr. Emily Peck, a no-nonsense MD and a potential business rival of Hank’s (Mark Feuerstein).

SPOILER ALERT! Griffith’s doc will be introduced during the USA Network hit’s second season (premiering June 3) when Boris (Campbell Scott) hires her to temporarily fill in for an MIA Hank.

As previously reported, Happy Days vet Henry Winkler is also joining the season 2 cast as Hank and Evan’s (Paulo Costanzo) absentee dad.

Griffith, who was also a fixture on FX’s Damages during its first two seasons, recently completed work on season 1 of Trauma. The struggling NBC drama is not expected back next fall.
