She has been hard at work shooting her lead role in the science fiction thriller film Mother/Android.

And now, after more than two months on the set in Boston, Chloë Grace Moretz flashed a big beaming smile on the final day of filming.

The 23-year-old actress also had a look of relief when she was spotted behind-the-scenes dressed casually in an all-black ensemble of pants, T-shirt and jacket.

As the day wound on, Mortetz hopped into the back of a military truck full of people wearing masks amid the still raging COVID-19 pandemic. 

The actress appeared to be in a hurry when she was seen walking past crew members on the set in Boston, Massachusetts.
