I keep hearing things about Joss Whedon putting an Angel reference in the Avengers: Age of Ultron movie. However, I cannot find what it is!
What is it?
In the Age of Ultron scene where Thor is freaking out due to Scarlet Witch's mind tricks, we see a reference to Wolfram & Hart, the demonic law firm from Angel.
(In the show, we find out that the firm descends from three ancient demons: the Wolf, the Ram, and the Hart.)
