5. James Gunnâs DC and Scooby-Doo Reference
In a fun twist, alternate Barryâs room decor features a throwback poster of the 2002 movie Scooby-Doo. Itâs a clever nod to James Gunnâs early Hollywood days, as he penned the script for the Scooby-Doo movie. This tasteful reference pays tribute to Gunnâs rise in the ranks, now proudly standing as the mastermind behind DC Studios, side by side with Peter Safran.
Moreover, a blast from the past moment in The Flash unveils a young Barry donning a t-shirt adorned with the iconic Mystery Machine logo from the Scooby-Doo series. Itâs a light-hearted gesture, subtly hinting at Gunnâs indelible imprint on the DC universe.

6. Temuera Morrison as Tom Curry
The Flash isnât without its fair share of delightful cameos, one of which is Temuera Morrison. Remember him from 2018âs Aquaman, where he brought life to Tom Curry, the dad of our aquatic hero?
As Barry takes a detour through an alternate dimension in The Flash, he reaches out to the Justice League and makes a call to Tom Curry. Hereâs the catch: Morrison reprises his role but with a twist. In this version, heâs married to a human, and his insight into Arthur Curry is limited to his canine companionâs knowledge, as the aquatic hero Aquaman was never brought to life.
