Arise, arise, riders of Rohan! Fell deeds awake, fire and slaughter! Spear shall be shaken, shield be splintered! A sword-day, a red day, ere the sun rises! Ride now, ride now, ride to Gondor! Ride for ruin, and the world’s ending!

When the eagles fly off with Frodo and Sam, there should be a subtitle of “In Eagle: Fuck yeah baby! Told you we had time for that haircut.”
"Do you think we should have flown straight here? We might have helped the hobbits get here .."
"Nah, bro. We look sick. We made the right call.
"Fuck, yeah, bro."
Frodo : "I will take it. I will take the ring to Mordor..."
Frodo : "...though I do not know the way."
Gandalf : "Fuck."
In the scene where Sauron's tower falls, I'd just scroll the word "fuck" from left to right.
It would be like poetry against this RoP scene (spoilers): 
I think I'd prefer an audible "F-U-U-U-U-U-U-U-U-CK!" as it was falling.
Or maybe afterward, pan to a lone goblin onlooker who just gives an exasperated "...fuck!"
When the Balrog’s whip snags Gandalf’s ankle.
Elrond: Cast it into the fire! DESTROY IT!
Isildor: Fuck no.
Boromir: "The trilogy has no f-bomb. The trilogy needs no f-bomb."
Fellowship: They have a fucking cave troll
Two Towers: To the fucking king!
Return of the King: Grond! Grond! Grond! - You're soldiers of Gondor. No matter what comes through that gate, you will stand your ground! ... Fuck
As he is getting air lifted by the eagles from mordor. "Fuuuuuuuuuucccccccckkkkkkk"
You shall not fuck!
I'm undecided about which is better.

or

"What about side by side with a fuck?"
"Aye, I can do that."
"I never thought I'd be fucking side by side with an elf."
"Aye, I can fuck that."
Not all of those that wander, fuck
Fucking run you fools!
