Joely Richardson is back to work two weeks after sister Natasha Richardson's tragic death. Joely, 44, returned to the set of the BBC remake of The Day of the Triffids yesterday, UK's The Mirror reports.

Look back at touching photos of Natasha Richardson.

Joely and Natasha's mother, Vanessa Redgrave, also stars in the flick -- but had already finished filming her role as Miss Durrant before the accident. (Redgrave postponed her appearance in a one-woman show in New York City.) Filming on the two-part thriller began last February, and goes through next month. Joely plays the female lead in the movie, which was adapted from John Wyndham's post-apocalyptic novel. She also stars in FX's Nip/Tuck.
