LOS ANGELES — FX is joining with “American Horror Story” producer Ryan Murphy on a true-crime anthology miniseries. First up: the O.J. Simpson murder case.

Each season of the miniseries, “American Crime Story,” will focus on a different crime that captured the public’s imagination, FX said.

The 1994 murder of Simpson’s ex-wife, Nicole Brown Simpson, and Ronald Goldman, and Simpson’s arrest and trial led to a prolonged media frenzy. The former NFL hall of famer and TV and movie star was acquitted in the case but is in prison for a hotel robbery.

FX did not announce the casting or air date for season one of “American Crime Story,” based on a book by lawyer and TV legal analyst Jeffrey Toobin.
