No, I think you're creating a class distinction where it's completely unnecessary (and a weird thought to even have, I think).

Theater, music (I'll assume we're not talking about "popular" music, but something more like classical music here), and literature tend to have known authors, and tend to have a wide variety of performances. (Although literature is weird to include in this list, I think).

Film, comedy (since it's differentiated from theater and film here, let's say stand-up comedy) and speeches have known performers. Authors in film are sometimes relatively well-known, but I think attributions to actors rather than characters in films aren't that common.
