Tina Louise Should Not Be Billed Last, IMDb!!

I don't know who is the stickler here for submitting that position, literally it is correct since she receives the final credit as "introducing Tina Louise" however this is not generally accepted as being billed lowest among the cast and is usually accepted in print as being billed immediately after performers who are given starring billing, which would be Robert Ryan and Aldo Ray so Tina should be billed third. Underlining this is everyone is billed on multiple name credits shots while only Tina is given a credit shot all to herself.
