It’s hard to imagine Stephen Hawking himself actually arrived while this scene was being filmed. He admitted that is was spectacular to see it, especially when the fireworks showed.
4:16 That must've taken every single ounce of willpower he had, after clearly stating dancing is not his thing. It shows his character as a person is not rigid.
Thank you, LWOPP. Sorry I took so long to see your question, Milly Mason. Although when I first saw the movie, I actually thought the piece was "When it's sleepy time down South" which was one of Louis Armstrong's signature songs. It sounds very similar.
There are three great songs in this scene: 00:24 “Blind Man Blind Man” by Herbie Hancock. 2:38 “Devil May Care” by Top Shelf Band, and 3:30 “I’m in the Market for You” (I believe the Archie Semple version)
Tbh, everyone, every second of everyday is quoting someone, rarely are any thoughts truly original. What is original is the collection of thoughts people have.
