Ruby Rose's time filming the pilot episode for Batwoman led to several medical incidents on-set that resulted in a slight redesign to the cowl.
While appearing on The Tonight Show Starring Jimmy Fallon to promote the new Arrowverse series, Rose revealed that after several days of filming in-costume as the eponymous superhero, she learned she was allergic to the adhesive tape used to keep the cowl to her face. As a result, Rose would break out into hives in affected areas after long days of filming.
Visibly noticeable by the rest of the cast and crew every time Rose removed it between filming scenes, the cowl was modified with cotton padding to prevent further outbreaks and irritations as production on the CW series continued.
In addition to the severe allergic reaction to the original costume, Rose herniated two discs in her spine filming a stunt sequence in the pilot episode, necessitating emergency surgery to avoid potential permanent paralysis resulting from the injury should it have remained untreated.
Written by Caroline Dries and developed by Berlanti Productions and Warner Bros. Television, Batwoman stars Ruby Rose, Rachel Skarsten, Meagan Tandy, Camrus Johnson, Dougray Scott, Elizabeth Anweis and Nicole Kang. The series will premiere on Sunday, Oct. 6 and air on Sundays at 8 p.m. ET/PT.
