Charisma . . . is not copyrightable.
SOFA Entertainment, Inc. v. Dodger Productions, Inc., No. 10-56535, slip op. 10 (9th Cir. Mar. 11, 2013) (Trott, J.) (holding that fair use doctrine barred copyright claim for showing of seven-second clip from Ed Sullivan's really big show in musical play about Four Seasons, which launched Frankie Valli's singing and dancing career).
Bonus: The court upheld an award of attorneys' fees for SOFA, the producer of Jersey Boys, because Dodger had tried pretty much the same thing with clips involving Elvis Presley.
