Adaptations
In Peter Jackson's The Fellowship of the Ring, There and Back Again comprised the basis for the voiceover for the scene "Concerning Hobbits", greatly extended in the Special Extended Edition. Bilbo's writing of it provides his motive for wanting privacy in the film, substituting for a more complicated situation in the novel.
Bilbo only says his line about his intended "happy ending" after he gives up the One Ring. The exchange is tweaked to symbolize the great weight of the ring having been removed from Bilbo's character — he is now free to choose his own 'ending'.
There and Back Again is subtitled A Hobbit's Tale rather than A Hobbit's Holiday.
The Red Book in full appears at the end of The Lord of the Rings: The Return of the King. Frodo's title is just The Lord of the Rings instead of The Downfall of the Lord of the Rings and the Return of the King.
