Angels and Demons [2009]

I'm ill. Really, I am.
This should be enough of an explanation.
Now, for the practical details:

Angels & Demons is a 2009 American film adaptation of Dan Brown's novel by the same name. It is the sequel to The Da Vinci Code, even though the novel Angels & Demons was published first and takes place before the novel The Da Vinci Code. Filming took place in Rome, Italy, and the Sony Pictures Studios in Culver City, California. Tom Hanks reprises the lead role of Robert Langdon, while director Ron Howard, producer Brian Grazer, composer Hans Zimmer and screenwriter Akiva Goldsman also return.
