Watch: Batman v Superman Ultimate Edition Easter Eggs
It's been a while since I saw the theatrical version, but one Easter Egg I thought I found in the Ultimate Edition referenced Red Hood -- when Bruce and Alfred were talking how there are no more good men in Gotham, or that good men turn bad (something like that). I thought it referenced Jason Todd going bad (perhaps the identity of the Jared Leto Joker?).
Screen Junkies also puts out those cool Honest Trailers.

Fearing the actions of a god-like Super Hero left unchecked, Gotham City’s own formidable, forceful vigilante takes on Metropolis’s most revered, modern-day savior, while the world wrestles with what sort of hero it really needs. And with Batman and Superman at war with one another, a new threat quickly arises, putting mankind in greater danger than it’s ever known before.
