Preston Dial
Isn't Preston Dial one of the many pseudonyms used in Charade?
shareCary Grant's aliases in Charade (before he finally reveals himself as "Brian Cruikshank") are -
"Peter Joshua"
"Alexander Dyle"
"Adam Canfield"
"Carson Dyle" is another name you hear in the film, but there's no "Preston Dial."
Thank you murph24! There is a well-known college football player this year named Preston Dial, and I was certain I had heard the name before.
But clearly not where I thought I'd heard it!
