The 2011 movie is a remake of the 1982 one, and I don't believe they should be in the same collection. Here is a quote from https://en.wikipedia.org/wiki/Conan_the_Barbarian_(2011_film):

The film is a new interpretation of the Conan mythology, and is not related to the films featuring Arnold Schwarzenegger.

Also:

In October 2012, Universal Studios and Paradox Entertainment announced that the next Conan production will not be a sequel to Nispel's [2011] film, and will instead be a direct sequel to the 1982 film, ignoring the events of both 1984's Conan the Destroyer and the reboot.

So The Legend of Conan, which will star Arnold, should be in a collection with the 1982 one. The 2011 one should hang alone.
