A town fair, a block of ice, and even the doctor are just some of the “Million Ways” to meet one’s demise in the American Old West, as “Family Guy” creator Seth MacFarlane lends his raunchy humor to parody the harsh conditions of life on the frontier. “A Million Ways to Die in the West,” out in U.S. theaters on Friday, is written and directed by MacFarlane, who also plays Albert, a hapless sheep farmer who is dumped by his girlfriend, befriends a mysterious newcomer and is challenged to gun fights.
