If you go to the very end of the video of this proposal (3:12), it says, “No fish were harmed in the making of this film.” It made me laugh.
Nicci is asked to host a show that tours the aquarium. Little does she know that it’s not an actual show. It’s a diversion. Keane has planned his proposal.
As she comes up on a larger tank, she sees two divers and starts questioning the camera-man. “What’s going on?”
“Are you getting this?”
It isn’t until about 1:25 when she starts realizing that it’s for her.
I laughed out loud when Keane asked her to marry him without kneeling, and you then see her instruct him to get down on one knee. While of course she said yes, I love that she wanted him to present it in the traditional stance.
