Bilbo has an adventurous spirit in his bones, and he is not timid, but after being occupied by many dwarves at home, he is restrained and restrained.
In fact, the reason why Iruba was destroyed was that the fire dragon plundered gold, not that Thror had fallen, so there was no need to emphasize his greed. Perhaps it is to explain that there is no need to mine and create so much gold without being greedy. If there is not much gold, the dragon may not come. However, the dwarves have always been obsessed with craftsmanship, so they can actually be interpreted from a positive perspective.
The fighting power of the dwarves was not too strong, and there were only 13 of them. Whether it is the first encounter with a troll, or falling into a cave and being captured, and finally encountering an orc. Three times, they relied on Gandalf to escape, which made people wonder if this group of people would really be able to return to Iruba alive without the gray robe wizard.
Bilbo basically didn't contribute much to the team except for the delaying tactics he used to deal with the trolls with basically no IQ. After falling into the hole, all the dwarves were tied up, but he was the only one who was ignored. In the end, risking his own life to save Thorin seemed a bit far-fetched. He could kill the Orcs, even if he was unprepared, he shouldn't be able to do it so easily. After all, the physical conditions are very different.
In addition, it was God's will that such a good thing as picking up the Lord of the Rings could fall on him. Moreover, Bilbo, who had been a good gentleman before, couldn't pick up the gold, so he could only use the things dropped by people to return them. It was explained by the equipment that was dropped by the ghosts.
In the end, Gandalf used the summoned beast when he was in distress, which was very unkind.
Trivia:
1. When filming The Lord of the Rings, the change in body proportions was accomplished through the illusion of depth of field and the hiring of dwarf actors, so Ian McKellen was still with the other actors during the filming. But when the film was filmed, it was filmed separately, with Ian McKellen filming by himself on a green screen alone, and only one earpiece was used to communicate with other personnel during the performance. This made the old man feel lonely and depressed. To keep him entertained, staff slipped into his lounge and decorated his room with Lord of the Rings memorabilia, including records and players so he could listen to music.
2. Daniel Radcliffe, Shia LaBeouf, James McAvoy, Erryn Arkin and Tobey Maguire were all considered for the role of Bilbo Baggins, but Peter Jackson insisted his first choice was Martin Freeman. Freeman originally wanted to reject the role because the schedule conflicted with "Sherlock", but Jackson specially adjusted the entire shooting plan in order to allow Freeman to play.
3. When asked how many wizards there are in total, Gandalf said that there are five wizards in one, besides him, Saruman and Radagast, there are also two wizards in blue, whose names he can't remember. The two men, Alatar and Pallando, appear in The Unfinished Tales, a book by JRR Tolkien's son that records his father's ideas and unfinished manuscripts. Since the producers did not have the rights to use the book, they had to skip the names of the two people with inability to remember.
4. Frodo (Elijah Wood), Saruman (Christopher Lee), Galadriel (Cate Blanchett) none of these characters actually appear in The Hobbit novels. Including Radagast (Sylvester McCoy), who is only mentioned slightly in the book, and actually appears in the "Lord of the Rings" book. However, his role in the "Lord of the Rings" movie series was deleted.
