Which Gave Me the Chance to Practice a Non-Rhotic Dialect and to Speak a Few Intrusive "R's"

Some kind of nasty sinus bug I've had over the weekend has rendered my writing skills useless for the past few days, but I have had the opportunity to watch The Departed (which I did not see on the big screen) on cable several times during the hiatus. As good as Goodfellas, in my opinion; although, how believable is an Irish mob boss in Boston wearing a Yankee's cap?
