All the woman who are saying Tom is Heathcliff take a cold shower
From what I've been reading here seems like most of the answers of the best Heathcliff are given by woman who are Tom Hardy's fans and all of you are dismissing Ralph Fiennes because he is not the heartthrob of your generation.
But com on girls how can you pick Tom hardy who is a descent actor over Ralph Fiennes who is a two times Oscar nominee.
Steven Spielberg picked him to play Amon because he saw his evil sex appeal in Wuthering Heights.
I think your pick is genuine but seems like all of you are thinking with your hormones and not with your heads.
So ladies please take a cold shower and check Both(1992 and 2009) versions again and I bet your pick for the best Heathcliff will change.
