Louisa Jacobson Reacts to Sister Grace Gummer’s Love Story Role

But while it was “really great” to be attending TV’s biggest night alongside her sister, the Materialists actress admitted that any potential project alongside Gummer and mom Streep isn’t coming any time soon. 

“We’re just all living our beautiful, individual lives,” Jacobson added, noting her family had nothing but “plans to support each other.”

As for how she manages to channel her inner 19th century woman when it comes to playing Marian Brook in the HBO period drama? Costuming goes a long way. 

“You’d think that the tight constraints would make it difficult but actually sometimes when you have a tight container, it allows you to be more expansive,” Jacobson detailed, “and certainly by season four that’s definitely the case.”

Although, a corset is actually her secret weapon on set. 

“It’s a constrained time in history especially for women,” Jacobson explained, “so putting on the corset just helps me get into character and helps me ease into that world pretty smoothly.”

On the red carpet, though, sh prefers to keep it in the 21st century, sporting a beautifully tailored black and white Tom Ford suit designed by Haider Ackermann. 

“It’s beautiful,” Jacobson mused. “I love it.”
