Tom Hardy steals the screen with any role he plays, he stars in a series called Taboo, very good, worth watching.
What I liked most about Rachel McAdams is her interpretation of Detective Ani Bezzerides in the second season of True Detective.
And Cobie Smulders, eternally Robin Scherbatsky, personally I will always love her. Every time I see her I say "I love you Robin". Her role as Robin in How I Met Your Mother is transcendental, I can't remember how many times she made me laugh and cry. I think Robin is the one character in a "comedy" series whose story has been so cruel and painful, Robin did get beaten up by life and she always knew how to get through it.
P.D: You are right about one thing: HIMYM is the best comedy series in the history of all comedy series in the world. it's scientifically proven!
