I was watching "Bewitchin Pool" the other day and someone dubbed that little girls's voice. It sounded like an older woman. Then everytime she'd go under the pool to that old woman, her voice would get normal. What was up with that???

I found it rather odd, as well. :nod:

Here's something from the episode's tv tome page that sheds light on why her voice was dubbed:

In the outdoor scenes, Mary Badham's voice was overdubbed by June Foray (who was the voice of Rocky the Squirrel) due to Badham's heavy southern accent combined with a high backlot noise level.

The Bewitchin' Pool (http://www.tvtome.com/tvtome/servlet/GuidePageServlet/showid-237/epid-12742/)

i really don't care about that i just love the episode :)

In the early days of televison it was quite common to have to dub voices in during post production if it was an episode with alot of location shooting. Many times the actors' voices could not be properly recorded during on location shooting, so sometimes entire scenes had to be dubbed in post.

i just love the episode:D

It's a weird episode as the ending of it is shown first for some odd reason.

so

..."The Bewitchin' Pool". I read Earl Hamner Jr.'s original script, and it WAS different from the version that was filmed. For one thing, the "confrontation" sequence [where Jeb and Sport declare they don't have to live with their bickering parents anymore and dive into the pool for good], which was written as the climax of the story, was also shown at the beginning because the final version of the episode came up a few minutes short (Whit's "Howdy!" greeting to Jeb & Sport as they emerge from the "swimming hole", and the tracking shot of the kids in Aunt T's yard were also repeated for the same reason). There were problems with noise interference on the MGM backlot during the pool sequences, and everyone had to be called back for post-dubbing...but Mary Badham wasn't available. So June Foray was brought in to dub "Sport's" lines at the session. It was a "sloppy" episode, and Serling knew it. That's why it was held until the very end of the season as the "final" episode {where most people wouldn't notice, having tuned out the series, anyway}.

:tv:

The multi-talented veteran voice actor June Foray has done much "looping" in
her long career (in addition to all those unforgettable cartoon characters like
Rocky, Natasha, Nell Fenwick, plus Granny and Witch Hazel in the Looney
Tunes). Miss Foray supplied the voices for two boys in Steven Spielberg's
"Jaws," extraneous characters for Burt Reynolds' "Cannonball Run" (in which
she did a couple of prostitutes), and a little boy who had been murdered and
had come back from the grave in "The Changeling" with George C. Scott.
She has even lent her voice to toys, such as the original Chatty Cathy dolls.
She was also the murderous Talky Tina doll in a memorable episode of THE
TWILIGHT ZONE ("I'm Talky Tina and I'm going to kill you").
