The Truth About Charlie is a 2002 remake of the 1963 classic film Charade. It is also an homage to François Truffaut's 1960 film Shoot the Piano Player complete with that film's star, Charles Aznavour, making two surreal appearances singing his song "Quand tu m'aimes" (first in French, later in English).
