Beyond the Valley of the Dolls - provide spoilers

My understanding was that they were running out of budget and time, and brainstormed an ending.

I know the two films have nothing to do with each other, but I'm not going to start a thread on the first one...I'm reading Steven Rebello's Dolls! Dolls! Dolls!: Deep Inside Valley of the Dolls, the Most Beloved Bad Book and Movie of All Time, so I thought I'd better look at the film again (saw it once a long time ago). It's not irresistibly bad. Patty Duke provides much of the camp, but mostly it's just slow and disjointed and boring. The weirdest thing for me is that the foundation of the film is supposed to be this great friendship between the three women, but they must have skipped that part when adapting the book--they seem to go from not knowing each other to some vague implication that they're lifelong friends who are always checking up on each other. Not sure if having Martin Milner play a press agent is supposed to be an inside joke going back to Sweet Smell of Success. Never knew Barbara Parkins is Canadian (and still alive).

Valley of the Dolls is perhaps the most inert "camp classic" of all time.

Meant to mention Richard Dreyfuss! One scene near the end, about 30 seconds, just like in The Graduate.
