My favorite medium of Looney Tunes is, without a doubt, the original shorts, especially in the late 30s to early 50s golden age. Throughout this page I make some reccomendations for original shorts, DC comics issues, and some Looney Tunes Cartoons (2020) which are currently being produced for HBO Max.
Some pieces of media I don't give individual reccomendations for here but are fond of are The Looney Tunes Show (2011), which is very different from the originals, but as its own thing is hilarious, and Looney Tunes: Back in Action (2003). The latter is controvrsial for having uninteresting human characters in the mix, but I do think that Joe Dante (dir) did excellent work with the toons-- he wrote Daffy very well mixing the screwball elements with his greedy personality (he even got to woo-hoo!). There's also half an hour of cut content (also put together into an unofficial "Director's Cut") for those interested in that.
The Dell comics of the 1950s have slightly different characterizations, but are really good at showing pairups that never made it to theatres (such as Bugs and Porky or more screwy Daffy and Bugs) if you can track them down.
Here is a collection of my favorite music that was featured in the original Looney Tunes shorts. My top 3 are Merrily We Roll Along, Ain't We Got Fun?, and You Oughta Be In Pictures
I have a strong preference towards Daffy Duck cartoons and Bugs Bunny cartoons still, but here are some select favorites from the new Looney Tunes Cartoons! They are super well-made and I really reccomend supporting them on HBO Max if you are able to!
Some quality TV Commercials from the 1960s Bugs Bunny Show. Several were directed by legends like Tex Avery (Kool-Aid commercials) and Bob McKimson (Tang commmericals)
(From 0:00 to 1:36) Cut content from The Gremlins 2 contianing a longer intro sequence with Bugs Bunny and Daffy Duck.
