1. Det. Sgt Dignam - The Departed (2006)
"My theory on Feds is that they're like mushrooms, feed 'em sh*t and keep 'em in the dark." The Departed is a fantastic film by Martin Scorsese and it has great performances in it by Matt Damon, Leonardo DiCaprio and Jack Nicholson. However, it is the small performance by Mark Wahlberg that everyone remembers as being the best. Sgt Dignam is a loud-mouthed, witty and mean detective who seems to outsmart almost everyone else in this film! His one-liners are hilarious and he puts the right people down, ridiculing them. It's a shame he isn't in the film a lot more but, I guess that is what makes him so brilliant; there aren't many scenes with him but the ones he is in are all great. At the end of The Departed, I genuinely cheered when I saw him again, appearing once more to give Matt Damon's character a final 'f**k you' before ending him! Mark Wahlberg's film choicea are often a little more than questionable but this film proves that he can be a great actor.
