Also, I'll admit that I followed a bit of the web controversy involving the event, its reporting, and maybe a rather obvious misstep or two about the lady's publicist as well as the examination of the events leading up to (and right after) the crash. Honestly, there's been a fair amount written and speculated about these events; and the bottom line so far as this human being is concerned is that none of us truly know what's going on in the private lives of anyone other than ourselves. While, yes, her behavior sounds as though she was a person in a major crisis in her life -- one that ultimately may have led to this tragic ending -- but none of us knows with any degree of certainty. All we really do is watch from afar ...
In that respect, Heche wasn't exactly one who trafficked in much by way of genre projects. I think she's far more well known for appearances in conventional dramas and comedies, of which I do recall a very, very good lead performance in TV's Life In Trees. (I watched that one with the wifey, and we got a good chuckle out of much of it, though it kinda/sorta veered into strange areas before concluding.)
Still, here's a review of the highlights I found in reviewing her IMDB.com resume.
In 1993, she certainly made a grand entrance into the realm of Fantasy with a guest role aboard TV's The Young Indiana Jones Chronicles. She was part of the adventure titled, "Young Indiana Jones And The Scandal Of 1920."
In 1997, she stepped even deeper into the realm of genre projects with a starring role opposite Tommy Lee Jones in the SciFi-lite Adventure/Thriller Volcano for Twentieth Century Fox. I recall seeing this one in theaters, not being all that impressed with it, but it was a serviceable enough flick that delivered on its promise.
In 2007, Heche voiced the seminal character of 'Lois Lane' for the first animated adaptation of the somewhat controversial Superman: Doomsday storyline. Though I think a lot of folks dismiss the whole Doomsday affair as a bit of a cash grab (i.e. killing off a main character only to resurrect him shortly thereafter), I've always enjoyed it ... and I think Heche did great work with Lane.
Also in 2007, the actress made a guest appearance in the single-season anthology program Masters Of Science Fiction. Her outing was titled "Jerry Was A Man," a tale that was adapted from a story by Robert Heinlein.
In 2008, she brought her brains and beauty to the role of a government doctor trying to uncover the secret behind an epidemic. Toxic Skies was written (in part) and directed by Andrew C. Erin, and it looks like this one had its first airing in Canada.
In 2016, Heche headlined a SciFi serial titled Aftermath. If I remember this correctly, I believe this was billed a one of those Syfy Originals TV series, and it explored a family in crisis now that Earth had been transformed by an apocalypse of almost Biblical proportions. Alas, it would seem that the show lasted only a single season, so I've no way of knowing if its characters truly made it out okay.
As is always the case when talent pass along, I find it refreshing that we'll always have the work to both discover and re-discover the marks made along the way.
Thoughts and prayers are extended to the family, friends, and fans of Anne Heche.
