I watched part of Bubble Boy again.  I love that silly movie.  LOL.
But I keep looking at the younger Jake and seeing a young Jack Twist.   You just want to grab him and hug him.     
That's the way I feel about 
October Sky, which I never saw until way after 
Brokeback. You can watch Jake do what's supposed to be a West Virginia accent, and you can hear Jack. But I like 
October Sky, and I actually found a copy of it on tape (  

 ) to give to my dad for Christmas, and he liked it, too.
I never got around to seeing 
Zodiac. The more I read about it, the less it seemed like my kinda movie. Plus, it was long, and reviews were mixed. I didn't see 
Jarhead until after 
Brokeback, and I don't recall seeing Jack in Jake's performance there.
As for Heath, I hated 
A Knight's Tale (I do medieval and Renaissance reenactments, so the rock music drove me around the bend). I'd like to see 
Casanova some day, but then I like "costumers." 
Candy and 
I'm Not There are definitely not my kinda movie.
