'another' is correct, as you are referencing only one other work by Pixar. So "Up" is another work by Pixar (in addition to Inside out). But if you meant to use Up as an example of other Pixar works, you would say, ..like "Up", and other works by Pixar. Meaning Up is one of several others you are referencing. So 'another' means one more, 'others, or other works' for more than one.
