Imagine taking your favourite family memories and spinning them into a full-length movie. That’s exactly what the Toronto filmmaker Seth Scriver has done with the animated documentary “Endless Cookie,” which he created over nine years with his half-brother Peter.

They join guest host Talia Schlanger to tell us how they bonded through filmmaking.
