Cullen's kids have talked about how their dad's role as Optimus Prime affected their childhood, and it's pretty cool. They've said that they used to think it was normal to have a dad who was a famous voice actor, and that they only realized how big of a deal it was when they started meeting other kids who were huge fans of the Transformers franchise.
According to Clancy and Angela, their dad was always very humble about his role, and never let it go to his head (unlike some other celebrities we could mention, cough, cough). They've shared stories about how he would often make them laugh with his impressions of Optimus Prime, and how he would use his iconic voice to command them to do their homework (okay, maybe that's a bit of an exaggeration, but it's fun to imagine!).
One of the funniest stories that Cullen's kids have shared is about the time they tried to record their dad's voice as Optimus Prime, but ended up with a bunch of bloopers instead. Apparently, their dad was trying to get into character, but they kept interrupting him and making him laugh, so they never actually got a good recording (oops, sorry dad!).
Despite the challenges of growing up with a famous dad, Clancy and Angela have said that they had a pretty normal childhood, and that their dad was always there to support them and encourage them to pursue their passions. They've also talked about how their dad's legacy has inspired them to give back to their community, and to use their own talents to make a positive impact on the world.
