TL: Bilbo trying to get the ring from Frodo.

TR: ???

BL: Galadriel going through her personal test of resisting the ring.

BR: Gollum following Frodo. .

From left to right : 1. Bilbo Baggins having one last craving for the ring when reunited with Frodo in Rivendell before the Fellowship takes off on its quest; 2. A lost soul in the Dead Marshes, a swampland Frodo and Sam need to go through on their way to Mordor; 3. Galadriel being offered the ring by Frodo in Lórien; 4. Grima Wormtongue, who poisons the mind of the King of Rohan on behalf of Saruman, but I can’t recall this scene in particular (and could also be mistaken).

Top Left: Bilbo snaps while trying to get the ring from Frodo in a moment of weakness at Rivendell in Lord of the Rings.

Top Right: The ghostly bodies under water in the Dead Marshes where Gollum is leading Frodo and Bilbo in The Two Towers.

Bottom Left: Galadriel refusing the ring from Frodo while freaking out and explaining how she’d become evil if she took it in LotR.

Bottom Right: Part way through Smeagol’s transformation into Gollum in The Return of the King.

I’m seeing two Hobbit-esque shots in the top left & bottom right, but I can’t immediately tell which films as it is entirely too early for me.

For the other 2, the blue looks familiar, but I can’t place either of them.
