In Finding Nemo, a clownfish named Marlin embarks on an ocean adventure to find his son, Nemo, who was captured by a diver. Along the way, Marlin teams up with Dory, a forgetful fish, facing many challenges that teach him to let go and trust others.
A popular fan theory suggests that Marlin’s overprotectiveness stems from the trauma of losing his wife and other eggs. This fear of losing Nemo again drives his intense need to protect him, even if it means being too controlling.
A key moment in the film is when Marlin realizes that he can’t control everything and that he must let Nemo find his own way. This moment changes their relationship and leads to Marlin accepting that letting go is part of being a parent.
What if Marlin had never gone on the journey to find Nemo? Would he have learned to let go and trust? A prequel could explore Marlin’s life with his wife before the tragedy, giving insight into his fears. A sequel could show Nemo growing up, possibly facing new adventures of his own.
