I'm a bit confused by the X-Men/Spider-Man/Farmers Insurance example. I think it needs a bit more context to explain how X-Men is relevant, rather than it just being "this actor had a role in an advertisement, which the characters in a movie that may or may not share a universe, may or may not have seen on TV". Does a Farmers Insurance ad with J. K. Simmons actually appear in the X-Men movies? Or was there a promotional ad for Farmers Insurance featuring the X-Men that included Simmons?
