Well he isn't that young either..
I mean Eliza is what in her early twenties? But she is playing a girl in her early twenties...
Jason is in his mid thirties...So he is at least ten years older then her...
Just a thought.
I think when you are used to seeing someone for so long looking a certain way you don't expect them to age.
Also he was in that accident so I suppose that could have aged him a little..you know going through all of that and all the rehab.
Personally I don't think that he looks that bad...
But hey..I am old...
