Martin Freeman would have been a much better Frodo. Elijah isn’t even in the top 100 list of actors that I would cast as Frodo.
The LOTR movies succeeded despite him.
Don’t get me wrong, I like Elijah. I just feel that he was miscast in those films.
They just took away all his good lines. Imagine movie Frodo laying down the law to Gollum:
I think if they had gone with the wise and courageous Frodo from the books then Elijah Wood would have been better at delivering this sort of line than Martin Freeman.
OH. Ohhh. Is that why Gollum cast himself into the fire? When was that line? Did that command just actually take effect?
No, I don’t think Frodo ever does tell him to jump.
More relevant is that Gollum swore an oath by the Ring not to harm Frodo, and Frodo warns him thay the Ring will hold him to his word cruelly. Then when Gollum does betray Frodo, Bam! Straight in the lava.
I believe it’s just intended to be foreshadowing of Gollum’s fate, not suggesting that Frodo actually used the ring on him.
