I posted a thread "Unexpected names from Film Noir" a little while ago. Which fits this theme.
Sam and Spade – iconic Bogart character from Maltese Falcon. I kind of like the alliteration and was thinking it almost makes a great fn/mn combo.
Thursby – as in Floyd Thursby also a character from Maltese Falcon.
Effie – LOVE this as a nn. also Maltese Falcon
Phyllis - as in the femme fatal Phyllis Dietrichson from Double Indemnity.
Norma Desmond – Desmond is usually all male to me but combined with an old classic like Norma I kind of like it as a mn for a spunky girl. Such a great combo from Sunset Blvd.
Orson - Orson Welles
Hedda - Hedda Hopper – Hedda could be a great alternative to the popularity gaining Hattie.
Astor – as in Mary Astor and the unrelated Gertrude Astor.
Wallace - as in Wallace Ford
Loretta - Loretta Young
Hedy - Hedy Lamar - She needs little introduction but could Hedy be a 1940's classy alternative to the Hattie?
My own personal favourites:
Ingrid (Bergman): My all-time favourite girls name and Miss Bergman certainly has something to do with it. She's in my top 5 of favourite actresses and she was just so lovely and incredibly talented.
Anouk (Aimee): Along with the nickname Anoushka which is just the sweetest. Also, Anouk Aimee's performance in 8 1/2 is one of my favourite performances of all time, she captures that role with utter perfection.
(Greta) Garbo: Greta is a bit too harsh-sounding, but Garbo isn't a bad name at all. Imagine having the last name of one of the most skilled actresses in the world, as your middle name. I think that would be pretty damn cool.
Olivia (De Havilland): The name Olivia actually always gives me an immediate association to Olivia De Havilland.
Katharine (Hepburn): I would name my daughter Katharine without blinking, and I would make her sit through Kate Hepburn's entire filmography so she could come to appreciate her incredible namesake.
Mary (Pickford): Silent film screen legend, who wouldn't want to be named after her.
Rosalind (Russell): Her way of pronouncing her name, is the only right way in my opinion.
Moira (Shearer): Her performance in The Red Shoes is one of my favourites of all time.
Hedy (Lamarr): Preferring it as a nickname for Hester or Hedwig (which was Lamarr's real name).
(Errol) Flynn: Prefer Flynn over Errol (aka the Weasleys poor owl).
Elvis (Presley): I probably wouldn't call my child Elvis, however, it's a really great name.
Archibald (Alexander Leach/Cary Grant): One of my absolute favourite boys names and obviously my favourite male Old Hollywood actor has something to do with just that. Imagine having an Ingrid and an Archibald and then having them watching the two flawless films that are Notorious and Indiscreet.
Vivian, Clark, Gable, and Greta all come to mind. Sabrina, as in the Audrey Hepburn character; Charlie and Chaplin, as in the silent screen star. I think old Hollywood I think: Lillian (Gish), Jean (Seberg and Shrimpton), Edie (Sedgwick), Clara (Bow), Louise (Brooks), Myrna (Loy), Fay (Wray), Gene (Tierney), Bette (Davis), Marlene (Deitrich), Marion (Davies), Veronica (Lake), Lucille (Ball), Mary (Pickford and Astor), Betty (Grable), Loretta (Young), Judy (Garland)...a lot of these last names are usable as well.
Marlena (Marlene Dietrich)
Marlene would get pronounced mar-leen though, not mar-layna and her real name was Marie Magdalene (swoon)
Marnie (Hitchcock character)
Elise or Elyse
Charisse (Cyd Charisse real name Tula Ellice)
Pier (Angeli) real name Anna Maria
Marisa (Pavan) twin of Pier Angeli, real name Maria Luisa
Jean (Harlow) real name Harlean
Grant (as in Cary Grant)
The first thing that comes to my mind is Marilyn (: We were considering about naming our daughter that but went against it. We hate the nickname possibilities with it.
