Sara Paxton would have a 4am call-time every morning as she required two-and-one-half hours to get her hair and facial make-up applied, and then another two-and-one-half hours to have her tail fitted.
Sara Paxton had to do a month of intensive swimming lessons in order to play the part of Aquamarine.
Sara Paxton's mermaid tail weighed over 100 pounds and was approximately 8 feet in length. It was crafted by the Australian makeup effects studio JMB FX, the same that created the tails seen in Fishtales (2007), H2O: Just Add Water (2006) and its spin-of Mako Mermaids (2013).
JMB FX Studio produced the mermaid tails for actress Sara Paxton. The tails were sculpted over Sara's body cast. Foam and silicone skins were produced for 4 tails, each tail was covered in over 5000 scales. A fully cable-controlled tail was also produced for the more complicated and subtle moves of the fluke that the suit tails could not perform.
