The German Stielgranaten - as well as other traditional German WW II hand grenades - did not have a ring and pin like the ones the Allies used, but had a string which had to be pulled hard in order to arm them. Thus they wouldn't make such a distinct 'ping' as they do in the movie. See more...
Through out the whole movie, all of the laser guns have the exact same sound effect as the gun Iron Man shoots out of his hands. See more...

Captain America: The First Avenger (2011) - 3 questions
The "questions" section is for any random questions that occurred to you while watching this film, or anything you didn't entirely understand, and which Google or the IMDb can't help with. Submit them as a question, and hopefully someone will answer (the bold comments in brackets) - check back regularly. If the answer is wrong, or missing information, please use the "clarify answer" option. Don't feel limited - want to know what music played in a certain scene? Whether this was the first film to use a certain effect? Here's the place to ask!
Question: It is made very clear in Thor that the safest place for powerful, mythical objects is Odin's weapons vault. So why would the Asgardians leave the most powerful and mythical of them all, the Tesseract on earth, behind just the push of a button?
Answer: As we have no idea of the circumstances behind the Tesseract ending up hidden in a Norwegian church, we can hardly say that the Asgardians have simply chosen to leave it there. Most likely the reason is that they simply don't know where it is; while they're powerful, they're certainly not omnipotent. If, though some unknown past event, the Tesseract was lost to them, then somebody took considerable care in concealing it, it seems entirely reasonable that the Asgardians would be completely unable to locate it and return it to their vault.
Question: When Captain America is rescuing the POWs, he's asked if he can get them out and he replies, "No problem. I've knocked out Adolf Hitler X times" (some large number I forget). I found it odd that he gave such a specific number. Is it maybe a reference to something from the comics (not just the number of War Bond sales pitches he has given)?
Answer: No, it was just the number of performances he's done. The number was specific simply because the line was funnier that way.
