What's interesting is that your timeline will likely have a POD in 1965 - making it earlier than any of ours (including mine, by about a year).
Assuming that you don't make it some formative incident from Morrison's childhood or the like, that is, which pushes it back even farther.
Definitely looking forward to your take on the late 1960s and early 1970s, naturally.
The POD will be a simple one he decides to focus on film, since he is in film school. He loses his interest in music and focuses his talents on film. So, the POD is while he is tending film school. As mentioned now I just have to figure out what films he would make. I def foresee his version of Lestat the Vampire. Of course with him performing the title role himself.
