Speaking about being introduced to the head of state Dame Helen said: "You're thinking 'its the Queen it's the Queen'," and when asked if she still got starstruck replied: "Of course, even more so I think because I feel self conscious, you know."
She added: "I am genuinely always astounded by her aura, her twinkle, her presence. It never fails to surprise me and again it's what everyone says when they meet her - it was what overwhelmed me the first time I met her."
Dame Helen was presented with an honorary fellowship award by the Duke of Cambridge at the Baftas last night and William joked about her portraying the Queen describing the performer as "an extremely talented British actress who I should probably call granny".
Speaking about her conversation with Kate, the actress said: "She said 'my husband called you granny last night' and I said 'yes that was so sweet'."
Hollywood star Thurman famed for her roles in a string of Quentin Tarantino films said about the Queen: "I have met some members of the royal family but never met Her Majesty - it was so overwhelming, it happened very quickly."
Arterton, a former Bond girl, said her parents were excited about her meeting the monarch and curtseying for the Queen was experience enough.
She said: "I've met everyone but the Queen, now I've got the full set."
