As currently designed, a Personal Film appearence doesn't appear on the person topic and only appears on the film topic (Al Gore for An Inconvenient Truth is a classic example, the only film appearance currently is for a Futurama show).
I've even at times forgotten its there when entering data (THX-1138 documentary springs to mind as a recent example I need to now correct all the acting performances to personal appearances).
That is weird. I can't remember our rationale, except that it probably involved the thought that "film appearances" is either too rare a property to put on "person" or would be too confusing, and that we hadn't thought of a good co-type. The personal TV appearance type probably has a similar problem. Suggestions for resolving this would be welcome.
I wonder if these roles can't just be part of film performance, already it has Himself/Herself (which I am not sure if there is a good distinction between itself and the default Personal Appearance role type).
Neil Patrick Harris plays himself in Harold & Kumar Go to White Castle. We could model that as him playing a fictional character named Neil Patrick Harris, who is in turn based on the actor… but “As Himself” is a well-established convention.
On the other hand, when Neil Patrick Harris is on The Tonight Show, he is making a personal appearance, not playing himself.
