For example, a new story thread where a wizard casts a spell to send Frodo or Samwise back to the second age, or perhaps a revelation that the lava in Mt. Doom acted as a portal that sent Gollum hurtling thousands of years into the past. Might be an interesting way to see some familiar favorites back in action.
shareHow about cross-franchise time travel? I would have the vat of molten metal in Terminator 2 act as a portal to the volcano in Mount Doom. When Arnold comes through it, he grows back his human skin via a magic spell, teams up in a sexless, father-daughter relationship with Guyladriel and together they deliver a major ass-kicking to the Orcs. Of course, Guyladriel always has to save the Terminator's butt multiple times per show, but hey, that's called progress.
shareThe T1000 fell into that vat too right? So I guess he's gonna show up in Middle Earth.
No match for Mighty Morfydd Power Ranger tho as she just turns him to stone with one stone cold bitch glare.
