I Can't Believe
...the recent classical music Baker's Dozen didn't include what has got to be the most overused piece in all of film: O Fortuna (Carmina Burana - Carl Orff)

When I clicked on the link, the first thing I associated the music with is The Omen (1976), but I looked it up, and, No. It is a familiar theme, but offhand I can't place it.
According to this, https://phoenixchorale.org/2013/04/music-from-the-silver-screen-behind-the-music-part-1/
"The song has been used for dramatic effect (and later, parody) in numerous films since including: Glory (1989), The Hunt for Red October (1990), The Doors (1991), Natural Born Killers (1994), The General’s Daughter (1999), Detroit Rock City (1999), Jackass: The Movie (2002), Cheaper by the Dozen (2003), and even G-Force (2009)." It also mentions Excalibur (1981) https://www.youtube.com/results?search_query=excalibur+o+fortuna
I've certainly seen some of those movies, but only The Hunt for Red October rings a bell. Excalibur would seem the best known example, but I guess it's been too long since I've seen it to recognize it.
I may do a Part II Baker's Dozen in the future.
