Back in 2017, Rebel, who appears as the character ‘Fat Amy’ in the movies, spoke about how filming the third installment made her conquer her fear of heights.

Appearing on the Late Night With Seth Meyers, she explained that the script required her to do a 20-foot (six-metre) free fall jump with co-star Anna Kendrick.

‘I know I seem pretty tough, but I am afraid of heights, that’s the one thing I’m afraid of, and I had to do this 20-foot jump ten times … and each time [I was] petrified [and] thought I was gonna die,’ she said.
