Wednesday's mystery celeb was January Jones!

Your first clue and corresponding Pycto referred to Jones's appreciation of sharks. Jones is a celebrity spokesperson for Oceana, working to save endangered sharks. The hint after solving this Pycto mentioned "Once Is Not Enough", a 1973 novel about January Wayne. January Jones was named after both this fictional character, and the month of her own birth.

The second Pycto was from 12 Angry Men, which, along with the hint after solving the Pycto, alluded to Jones's role as Betty Draper in Mad Men.

The third and final Pycto mentioned its subject, Bellatrix Lestrange, shared a name with the mystery celeb's own "Dark Mark", or tattoo. Jones has a tattoo that reads "Bellatrix", the Latin word for female warrior.

The final hint given by solving all three Pyctos stated that the celeb you were looking for portrayed a character from Marvel Comics, and had an alliterative name. January Jones portrayed the mutant Emma Frost in X-Men: First Class. Since Tessa Thompson also matched this clue, I did not penalize anyone who provided that answer first.
