Place this near the end of a comeback sequence, after the low point and just before the resolution shot. Follow it with the hallelujah meme sound for a sincere lift, or swap that for a clapping sound effect when the return is played for laughs with friends watching.
About this sound
Mufasa speaks the line 'remember who you are' to adult Simba in a deep, calm voice over about five seconds. It feels warm, solemn and quietly powerful, like a father steadying his son. The clip comes from Disney's 1994 animated film The Lion King, during Mufasa's spirit appearance, voiced by James Earl Jones.
