They’re not especially similar. I think the talking style is very close, people say it is flirty in the same way as the film. You can’t copyright look and feel though, can you?
You can certainly patent it.
"In general terms, a “utility patent” protects the way an article is used and works (35 U.S.C. 101), while a “design patent” protects the way an article looks (35 U.S.C. 171)."
Microsoft argued in court that you can not and won. See Apple vs Microsoft if I recall correctly.
