Toni Collette is one of Hollywood's hardest-working actors. The Australian actor began her career in the early 90s and rose to prominence with the 1994 romantic comedy Muriel's Wedding before receiving her first Oscar nomination for her performance in The Sixth Sense.

Now. Collette is at the height of her career, starring in movies and television, taking both lead and supporting roles. Last month, she debuted The Power on Prime Video; this week, she has the comedy Mafia Mamma (premiering on April 14) on the big screen. And while not all of her projects are hits, many are critical darlings, earning high scores in the review aggregator Rotten Tomatoes.

Collette earned some of the best reviews of her esteemed career for Hereditary, with many considering her performance Oscar-worthy and decrying the Academy's choice to snub her.

9 'Dinner With Friends' (2001)

Rotten Tomatoes Score: 90%

Dennis Quaid, Greg Kinnear, and Andie MacDowell star opposite Collette in HBO's 2001 acclaimed made-for-TV movie dramedy Dinner with Friends. Adapted from the eponymous 1998 play, the film centers on a seemingly perfect couple whose life unravels after learning their best friends are getting a divorce.

Elevated by the committed performances of its four talented actors, Dinner with Friends is an insightful and thoughtful portrayal of intimacy and relationships. It's far too similar to the play, to the point where there are only four main characters throughout, but it remains a fascinating dissection of adult relationships powered by clever writing and four compelling performances.

The Staircase attracted acclaim from critics. Firth and Collette received near-unanimous praise, earning Emmy nominations for their performances.

Rotten Tomatoes Score: 95%

The 2000s produced many great underrated movies, but few were as insightful or touching as the 2009 stop-motion masterpiece Mary and Max. The story chronicles the pen-pal friendship between eight-year-old loner Mary and Max, an overweight forty-four-year-old man with Aspergers. The film spans decades, so Collette voices the adult version of Mary.

Mary and Max received universal acclaim. Critics praised the stop-motion animation, themes, emotional weight, and voice cast. Philip Seymour Hoffman and Collette's voice work earned significant praise, as did the film's screenplay and heart-wrenching ending.
