It is rumored that Ridley Scott’s “Prometheus,” out Friday, is a prequel to “Alien,” but Scott has been coy. (Wouldn’t it be funny if it were actually a prequel to “Blade Runner”?) Anyway, many films go back to the start of an already-told tale.

Red Dragon
This 2002 Hannibal Lecter film features two terrifying performances: Anthony Hopkins reprising his role from “Silence of the Lambs” and Ralph Fiennes as Francis Dolarhyde, a serial killer on the loose.

X-Men: First Class
This 2011 prequel about the formation of the superhuman crime-fighting group wasn’t perfect. (COUGHJanuaryJonesCOUGH.) But it was fun, even if Michael Fassbender’s Magneto occasionally sounded Scottish.

The Good, the Bad and the Ugly
This 1966 Clint Eastwood classic traces the beginnings of his iconic Man With No Name. You can see him taking on the costume that will be familiar to fans of “A Fistful of Dollars” and “For a Few Dollars More.”

The Hobbit: An Unexpected Journey
Yes, this comes out this December. Yes, we already know it’s going to be amazing. It goes on the list.

Indiana Jones and the Temple of Doom
Taking place a year before “Raiders of the Lost Ark,” this 1984 installment in the Indiana Jones series was long considered the weakest. Then “Kingdom of the Crystal Skull” came out.
