The brother-sister duo is working together in a Bollywood movie for the first time.
"Eid Mubarak. Missing everyone back home but first day of shoot for @Saqibsaleem and I... Small ways God lets us know he is watching and blessing," she posted on Twitter.
The yet-untitled movie, like the original, focuses on the story of a brother-sister, who get separated at a young age due to an antique mirror.
The film is being shot in London.
Huma, 28, was last seen in "Badlapur", while 27-year-old Saqib's on-screen previous outing was "Hawaa Hawaai".
