Just to expand upon the comments by Dr-RJP, I wanted to comment on the great casting in Rescue Me. I was recently watching Denis Leary's movie The Ref (also starring Kevin Spacey) and recognized at least two of the actors from Rescue Me in the movie, in small roles. Obviously Denis Leary believes in loyalty and attempts to surround himself with familiar people when given the chance to cast his own show. This is also evidenced by the recently-released Comedy Central Roast of Denis Leary, in which he pays homage to Lenny Clarke, who plays Tommy's uncle Teddy in Rescue Me and was also an integral character in Denis' short-lived ABC series "The Job". Anyone who enjoys Denis Leary's brand of humour should watch "The Ref" - it's an under-appreciated comedic gem and a great Christmas movie as well!
