In "Walk the Line" Joaquin Phoenix has the unenviable job of recreating one of the most distinctive personae in the history of pop culture; there are simply few figures more iconic and instantly recognizable than Johnny Cash.

The real Johnny Cash appeared as himself in dozens of movies and TV shows, and his music has appeared in every kind of film — from western to comedy, drama to horror. (The use of "The Man Comes Around" over the main titles of 2004's "Dawn of the Dead" was nothing short of genius).

But Cash only ventured into acting a handful of times, and while his is certainly a mixed legacy it's also worth a look.

Cash first acted onscreen in the 1961 cult thriller, "Five Minutes to Live," a.k.a. "Door to Door Maniac," playing Johnny Cabot, a pompadoured troubadour-turned-killer. In the film, he teams up with a con man named Fred (Vic Tayback) to kidnap a bank president's wife. Problem is, the bank president is leaving his harping wife for another woman and has no interest in paying the $70,000 ransom for her safe return. Cash is competent, if campy, and has some swell lines like, "This suburb life ain't for me."

Cash's next big screen role found him facing off against Kirk Douglas in "A Gunfight," (1971) a cynical postmodern western in which two jaded, aging gunfighters decide to sell tickets to one last showdown. (What kind of service charge is there on something like that?)

Despite a powerful presence, Cash never quite mustered the acting chops necessary to really fill the big screen and was, paradoxically, far better suited to acting for television. In 1962, he played Johnny Laredo in a western pilot called "Night Rider" (not to be confused with Hasselhoff's talking-car opus). 1978's "Thaddeus Rose and Eddie" is notable in that it was the first time that Johnny co-starred with his wife, June Carter Cash (who played his girlfriend). Probably encouraged by her on-set support, Johnny would subsequently bring June along for the ride many more times.

More TV movies followed, including "The Pride of Jesse Hallam" (1981), starring Cash as an illiterate Kentucky miner who has to learn to read when he moves to the sprawling metropolis of, uh, Cincinnati. In 1983's "Murder in Coweta County," Cash is a sheriff who brings to justice an amoral killer played by none other than Andy Griffith. In the wake of Kenny Rogers' enormous success with "The Gambler," "The Baron and the Kid" (1984) found Cash playing a pool hustler who reunites with his long-lost son.

In the late '80s, Cash returned to TV-movie westerns. He strapped on the holster as an aging Frank in "The Last Days of Frank and Jesse James" (with Kris Kristofferson as his outlaw brother), "Stagecoach," "Davy Crockett: Rainbow in the Thunder" (1988) and 1998's "All My Friends are Cowboys." Cash also had a small part as the abolitionist John Brown in the 1985 Civil War mini-series, "North and South."

But Johnny Cash the actor seemed far more relaxed and comfortable when he wasn't carrying the dramatic weight himself, and his most enjoyable, entertaining roles emerged when he guest-starred on series television.

In "Swan Song," a 1974 episode of "Columbo," Johnny plays ex-convict/country gospel singer Tommy Brown, who, while fronting a Christian act, doesn't practice what he preaches. Tommy drinks, cheats on his wife, Edna (Hollywood powerhouse Ida Lupino), and longs to play more secular arenas. He drugs Edna and his mistress (a young backup singer) during a small-craft plane flight, then parachutes to safety as it crashes, killing the women and seemingly solving his problems. As always, the disheveled, titular L.A. detective (Peter Falk) isn't fooled for a second, and sets about cracking Cash's alibi. As Brown, Cash gets to draw on the gamut of his experiences — saint and sinner, idol and adulterer, a man truly steeped in black. It's a total hoot and, arguably, stands as Johnny Cash's finest moment as an actor.

In a 1976 episode of "The Little House on the Prairie," Cash plays Caleb Hodgekiss, a man who assumes the guise of a reverend in order to raise money and supplies in Walnut Grove, ostensibly to help the victims of a fire in a neighboring town. In fact, Caleb plans on keeping the booty for himself and his wife Mattie (June again), but all those hearts o' gold teach him the error of his ways.

One of Cash's final acting roles was in the form of a short but sweet voiceover. In a classic 1997 episode of "The Simpsons" — "El Viaje Misterioso de Nuestro Homer," Homer has a hallucinatory experience after eating "Guatemalan insanity peppers" ("grown deep in the jungle primeval by the inmates of a Guatemalan insane asylum," according to Chief Wiggum) and is visited by a coyote spirit guide, voiced by Cash. The coyote, when not chewing on Homer's pant leg, instructs him to seek his true soul mate, intimating that it might not be Marge. It's a tiny part, but hearing that aged, distinctive baritone emanating from a mystical beast summoned by delirium and psychotropic enzymes seems somehow fitting.

Also in the late '90s, Cash had a recurring role as Kid Cole on "Dr. Quinn, Medicine Woman" and made an appearance on the Lorenzo Lamas biker-fugitive show, "Renegade."

Unlike, say, Frank Sinatra or Will Smith, however, Johnny was never fully believable as an actor. Maybe his instrument, his unique voice, was only genuinely suited to telling stories through music. In that role, Johnny Cash was as riveting a performer as anyone who's ever lived. We wish Joaquin luck.
