I thought the voice-overs of both older Dottie and older Kit were ridiculous. That wasn't done with any of the others. Did they think we wouldn't know who Kathleen Butler (older Kit) and Lynn Cartwright (older Dottie) were supposed to be?
You matter. Unless you divide yourself by the speed of light squared. Then, you energy.

I found the Dottie voice-over to be distracting. While it was synced pretty well, it was still obvious from the very first lines the old Dottie uttered. They really should have just slapped old lady makeup on Geena Davis.

I feel like there are only subtle differences in voices as people age in general. My grandmother sounded the same for thirty years. Inhave video to prove it.

Geena Davis didn't add any aging to her voice, which I thought was a mistake. Still sounded exactly like young Dottie.
Science doesn't care what you believe.

I was surprised too. I thought it was Geena Davis in make up to make her look older!

yeah different actresses, but the originals dubbed their over their lines.
It's kinda weird how you can sometimes associate actors looking older via makeup as more normal , than seeing someone completely different but hear the original voice.

As Lovitz used to say on SNL -
"ACTING!"
