I noticed that also missing from your list is Julie Strain, B-movie actress and model (though she recently retired to be a full-time mom). She's 6'1"... or as she puts it, "Six foot one and worth the climb."
I don't see Ali Larter (Heroes) in your list anywhere. She's 5'8".
Yet another I've found from the east side of the Pond - spotted in Mad About Your ... Helen Hunt, film actress who is also 5'8". Plus Jamie Luner guested recently in rerun of NCIS that I saw and I noticed she appeared quite tall. Indeed, she is 5'9" (same as me if you round up!) :)
Jayne --- Thank you for two more tall additions. I have just added them to the list.
