Chloe Bennet, who is an actress and plays one of the lead characters on Marvel's Agents of S.H.I.E.L.D (an enjoyable show, one I have watched personally), says this about why she changed her last name:
"It means I had to pay my rent, and Hollywood is racist and wouldn’t cast me with a last name that made them uncomfortable,"
Her surname by birth is Wang.
Apparently she didn't think she'd get a job with a Chinese surname.
I'm just going to point out that one of the other main characters, who has appeared in every single episode just like Ms. Bennet, is the actress who plays Agent May.
That is all.
