DC vs. Marvel (or: incessant hollywood incest) OR Six Degrees of Dawson Leary

I cracked up laughing a few years ago while watching the film Wonder Boys an realizing that there is a scene where Toby Macquire ends up in bed with Robert Downey, Jr AKA - respectively - Marvel's SPIDER-MAN and IRONMAN. Since then a lot of actors have taken
Roles in DC or Marvel films and the intertwining nest of incest has just gotten stranger and stranger... Off the top of my head:
(might just be easier to make a video?)
not sure if it even matters were we start, so I will start with...

The Amazing Spider-Man

AKA

Andrew Garfield 

first seen acting across from 

Health Ledger 

AKA

the Joker 

in that weird Terry Gilliam film

(the Cabinet of Dr. Parnassus?)

Anyhow,

Ledger

AKA

the Dark Knight's

Joker

first becomes famous in the late 1990s 

for his role in 

10 THINGS I HATE ABOUT YOU

where he schools the young 

Joseph Gordon-Leavitt

AKA

Robin "John" Blake

selected by BATMAN himself 

to become the presumed

heir to the Dark Knight's throne as

NIGHTWING in The Dark Knight Rises.

Ledger, 

lover of Jake Gyllenhall's

character who ignored

Anne Hathaway

AKA Catwoman's

advances in Ang Lee's 

Brokeback Mountain

-or whatever happened- who remembers

anyhow,

Jake, real-life

brother of 

Maggie Gyllenhall who

took over for the role of 
BATMAN's love interest

formerley filled by 

Katie Holmes who was also the

love interest of 

Toby Macquire

AKA

SPIDER-MAN

in both the films

the Ice Storm

and

Wonder Boys 

when he goes to bed

with 

Robert Downey Jr

AKA

IRON MAN.

Not to mention is 

the Ice Storm he is obsessed 

with the Fantastic Four...

of whom

Chris Evans

was the Human Torch

but who also reappears 

as Captain America, 

an Army subordinate of 

Tommy Lee Jones, 

AKA Two-Face in 

Batman FOREVER.

Evan's fellow Avenger, 

HULK,

also appears in a

film of the same

title

directed by Ang Lee.

There are probably more,

this is probably just the tip of the iceberg

I mean, shoot, Kenneth Branaugh 

directed THOR...
not to mention Gwenyth Paltrow and Samuel L. Jackson... 

but like I said -

that was just off the top of my head.

I'll stop here.

Might I also add that - in the Bret Easton Ellis universe- Sean Bateman (aka actor James Van Der Beek aka Dawson Leary) is brother of Patrick Bateman aka American Psycho aka Chrisitan Bale aka Batman - and Dawson's girl-next-door / true love is Joey Potter aka Katie Holmes aka Rachel Dawson aka Christian bale Batman's girl-next-door / true love. Yep.
