Eddie writing the V on his cast to make "LOSER" into "LOVER"
I didn't realise it myself, but it's been pointed out to me by my sister (when we saw the movie in 4DX yesterday) that the V is practically identical to that of the 1984 V Miniseries about the alien visitors with a hidden agenda:

Isn't that V logo uncannily like the one on Eddie's cast? Was the director trying to point out something or make a reference? Or was it just coincidence?
Then again, the IT movie logo is written in the same blood-red dripping spray paint style, so perhaps it's as simple as that?
In any case, I like the idea that Eddie Kaspbrak fancies himself something of a Casanova.
