my comic geekdom has been exceeded by this reader:

The last e-mailer got it partly wrongn (and that Hulk
Encylopedia from Marvel comics is so riddled with
errors it makes the mind boggle).
David Banner was the name given to Bruce Banner’s dad
in the recent Ang Lee movie. PAD (Peter David) gave
Bruce’s dad the name “Brian Banner” – this allowed for
a neat cover trick on the special issue Hulk minus
One, where a dead body with a hidden face lies on a
grave, and the tombstone reads “Who killed B_____
Banner?” – this was meant to make you think someone
had killed Bruce Banner, when really it was Brian
Banner who died.
Also, according to the audio commentary on the DVD for
the Hulk TV pilot, Kenneth Johnson said it was NOT
because Bruce was “too gay” of a name, but because the
alliteration was “too comic book-y” – though he did
put “David Bruce Banner” on the tombstone as a tip of
the hat to the comics.
