Dominic Purcell to Guest Star on Castle
Having broken out of prison years ago, Dominic Purcell has finally found his way back to the small screen.
The former Prison Break star will appear on an upcoming episode of Castle, one that finds Beckett and Castle heading to Los Angeles for an investigation. Once there, the duo will run into Purcell's character, a businessman with possible ties to the murder.
The installment will air in late April or May.
