One of the fascinating pieces of trivia below is true*, the other is false. Do YOU know which is which?

Captain America: The First Avenger (2011)

1) Even though the vial of serum stolen by the Hydra agent is broken, another showed up in The Incredible Hulk to be injected into Emil Blonsky (making him the Abomination). You can even see “Vita-Ray” written on the refrigerated storage container. According to canon many attempts were made to replicate the Super-Soldier experiment, but for a yet-unexplained reason it only ever worked on Steve Rogers and Johan Schmidt. 

2) Hugo Weaving refused makeup for his role as The Red Skull, instead having all of the skin and hair surgically torn off of his head and his skull dyed the perfect shade of Nazi red. Unbeknownst to Weaving at the time, the procedure was irreversible, which is why he now wears his V for Vendetta mask everywhere he goes. Not to be outdone, Chris Evans refused to use any CGI or camera trickery for his scenes as a skinny Steve Rogers, so after filming his scenes as Captain America, he went on a strict diet of inhaling flatulence from a sherpa who captured it in a jar on the top of Mount Kilimanjaro, which was then airlifted to Evans each afternoon. Evans also shrunk his musculature each day by wrapping himself in duct tape that had been soaked in rattlesnake venom and urine. Evans lost 120 pounds in nine days using this technique, but to this day the only way he can go to the bathroom is by having a cat bite him on the scrotum.
