Instant Family’s Lizzy Is Played By Isabela Merced
The Actor Was Credited As Isabela Moner At The Time
Isabela Merced (then credited as Isabela Moner) takes on the role of Lizzy inInstant Family, delivering a performance that is one of the highlights of the movie.Lizzy is introduced as a rather blunt young woman who is a teenager in the foster care group, which means she has few expectations of finding a family to take her in. To complicate her situation, she refuses placement unless the family also takes her younger siblings with her. However, much to her surprise, the Wagners agree to the match.
She is very protective of her younger brother and sister, serving as their parent in many ways for most of their lives.
Merced is excellent at playing the complexities of Lizzy. She is very protective of her younger brother and sister, serving as their parent in many ways for most of their lives. She is therefore reluctant to step aside and allow Ellie and Pete to take over as the parents. She also hopes to reunite her and her siblings with their birth mother, which makes her very reluctant to get attached to the Wagners. On top of that, she finds herself in many teenage situations, making questionable romantic choices, sneaking out with friends, and generally rebelling.
Merced shows the layers of this intelligent and conflicted young character in her performance. Merced makes Lizzy a frustrating character as she lashes out at Pete and Ellie, two people who are just trying to help her and her siblings. However, she also shows the audience why she acts out like this, making her sympathetic at all times. Merced’s performance in the climax of the movie is one of the highlights of the film.
