Question: It's common knowledge (and stated in the movie) that O, Brother, Where Art Thou? is based on the Greek Epic The Odyssey by Homer. Most of the O, Brother characters have parallels in The Odyssey. But I can't find anyone who seems to match the bank robber George 'Babyface' Nelson. George Nelson was a real bank robber, so it's possible he was just part of the story, and wasn't necessarily taken from The Odyssey... but I'm hoping there's a connection I'm missing.

Answer: Does Babyface Nelson represent anyone from The Odyssey?

Question: In Iron Man 2 (2010), Whiplash (the villain) enters as a track marshal during a race on the Grand Monaco Racing Track, unleashing his weapons on Tony Stark when he's most vulnerable. But, Tony only decided to race the Stark car minutes before the race, which Whiplash couldn't have known. Was he able to predict that it was going to happen or is he that lucky? Then, how could Whiplash come so prepared without knowing that?

Answer: How did Whiplash know that Tony Stark is going to the racing track?

Question: In Interstellar, when Murph visits her brother and his wife, she notices that their son is coughing hard, and she offers to arrange a visit from a doctor for him. The brother and his wife refuse, however, even though she warns them their son will die otherwise. Did it signify anything? I thought that maybe it signified that there is an anti-science movement because of the blight. The brother certainly seemed to dislike his father and sister's scientific pursuits.

Answer:
Why did Murph's brother and his wife refuse a doctor for their son in Interstellar?
