Question: Who is the actress playing the flight attendant that listens to the guys in the bathroom with disgust?
Answer: Lara Cox is not the flight attendant. "Cute Girl on Plane" was the 2nd girl to enter the scene and overhear the boys in the bathroom. I was unable to find who played the flight attendant and she may have just been a featured extra. I suspect Lara Cox is a member of S.A.G. and that's how she got a credited role and the other lady is not a member and was just hired as a background actor, which is why she's not credited (most extras are not credited).
Answer: If I'm able to figure out who the correct person is by the IMDb listings, I think she's credited as Cute Girl On Plane, with the actress playing her being Lara Cox. That's the closest thing I could find in the IMDb listings to a flight attendant, as I don't think customs officer counts.
Question: Dr. Claw's claw has a red light built into it. During the film it is shown to be flashing. I've just always wanted to know what this means?
Answer: Probably just a common trope seen in movies to indicate something is on or working. It adds a hint of in-movie realism. While it's shown that the claw can be operated manually or through will, it isn't implied the light does anything or tells us anything.
Question: Is the taxi driver the cosmonaut from Alex's youth? First he states that he's always mistaken for the cosmonaut, but then he tells Alex what's it like to be in space.
Answer: According to IMDb, Sigmund Jähn gave permission to be featured in the movie, but refused to play himself. It was very difficult to find an actor who looked like Jähn and spoke his typical dialect but after filming had begun, 'Wolfgang Becker' chose a Swiss actor. He was given complex make-up and was dubbed by another actor who came from Jähn's home region, the Vogtland.
Question: What is the name of the song at the beginning of the credits?

Question: How did Kate Hudson pay the cab fare after she left Mathew McConaughey's apartment, after she left her pocketbook in the apartment?
Question: Steve Zahn's character avoids being in the prison population by repeatedly hitting the prison guards and ending up in solitary confinement. Wouldn't assaulting a prison guard also add time to his sentence?
Chosen answer: It could, but they would have to bring charges against him, and have a new trial for that crime. It would most likely prevent him from getting a early parole.
Chosen answer: Designs of torpedoes dating back to before World War Two were generally capable of exceeding thirty knots, with many current designs easily doubling that and, in certain cases, reaching well into three-figure territory. The Juliet-class torpedo appears to be fictional, but, given the performance figures for real life designs, a speed of thirty knots seems actually quite slow.
