Actors, actresses put in a lot of work to make sure they epitomise their characters and bring their persona to life in all facets. Practising and memorising lines, mimicking voices, and stunting are a few of them. But what about body transformations?
Here are some notable Hollywood body transformations that will leave you gaping.
Mark Wahlberg
‘Transformers’ and ‘Two Guns’ star, Mark Wahlberg recently reminded movie fans that certain movie roles require dramatic body transformations and enormous dedication. On Monday, May 3, 2021 the 49-year-old actor took to Instagram to share a collage of his drastic body change.
The Oscar-nominated star showed off the toned physique he’s known for in one snapshot, while the other image displayed his 20-pound weight gain for his upcoming film, Stu.



“From left photo 3 weeks ago to this, now,” The Fighter actor wrote, adding a sweet shout-out to his chef, Lawrence Duran. “Thanks to @chef_lawrence_d cooking.”
Mark’s post received many comments, including a cheeky one from his wife of over a decade, Rhea. “And it looks just as hot in person baby [red heart emoji],” she replied.

Joaquin Phoenix



Remember the Joker origin story? Yep! Phoenix opened up about his 52-pound weight loss, telling the Associated Press, “Once you reach the target weight, everything changes.
