The workout-averse Jones lifted some weights for the role, but otherwise struck flattering poses and hoped for the best. She did have some advantages over the other actors when it came to costumes. “I don’t have to do all the crazy prosthetics,” Jones said. “When I morph into my diamond form, it’s all done on computer.”

One of the first things Jones wanted to understand about her character was the source of Emma’s anger, an answer she found by steeping herself in “X-Men” lore.

“Emma was a bespectacled, mousy child who had this power when she was young that she couldn’t quite harness, the telepathy, the mind-twisting stuff,” Jones said. “She had a falling out with her father and went her own direction.”

It wasn’t just learning Emma’s back-story that was important to Jones, but being able to reach hard-core fans. “Fans of the X-Men comics have a very set idea of these characters in their heads,” Jones said. “I wanted to know as much as I could about her so I wasn’t disappointing anyone. I’m sure I will still disappoint someone.”

Okay, but I wouldn't be a true X-Head if I didn't point out that Emma doesn't gain her diamond power until later... Waay later. But I hope Janny pulls this off.
