It's still hard to see Heath in Ennis. When I look at those pics of course I know it's Heath who played Ennis, but to me, it IS Ennis, not Heath.
Guess this derives from the feeling of Ennis and Jack being so real, not fictional characters.
When I see Casanova, oh yes, that's Heath playing the character of Casanova, or it's Heath playing Gabriel Martin, or Dan or whatever character. Not with Ennis. Ennis just IS period.
