Series creator Danny Antonucci directed the film and co-wrote it with Jono Howard, Mike Kubat, Rachel Connor and Stacy Warnick.

Big Picture Show centers on an adventure that the adolescent Eddy takes his friends Ed and Edd with him to find his older brother after their most recent money-making scheme leaves their cul-de-sac in a state of devastation that harms its other participants.

It stars Matt Hill, Sam Vincent and Tony Sampson as the title characters, and David Paul Grove, Kathleen Barr, Erin Fitzgerald, Peter Kelamis, Janyse Jaud and Keenan Christenson as their neighbors from the cul-de-sac.

While Jimmy and Sarah were not involved or affected by the scheme, they seek to have a picnic and watch the Eds get beaten up, but run into the Kanker sisters — Lee, Marie and May.

Elsewhere, Nazz throws Kevin's bicycle into a tree upon losing patience with him prioritizing it over her well-being and not noticing how she feels over this while Jimmy and Sarah escape from the Kankers and find Wilfred, who accompanies them for the rest of the trip.

The Kankers abduct Kevin, Nazz, and Rolf before the Eds locate a coastal theme park the next morning called "Mondo A-Go Go", which matches a postcard Eddy has from his brother.

Now expressing remorse over his past actions, Eddy tearfully reveals that he lied about his brother and conducted schemes in an unsuccessful attempt to gain admiration and social acceptance.

He decided to cut the sixth season short so they could focus more on creating this movie, entitled Ed, Edd n Eddy's Big Picture Show.

Daniel Sioil as well as Ruth Vincent served as producers while Ken Cathro was its editor and Scott Underwood, Steve Garcia, Raven Molisee, Joel Dickie and "Big" Jim Miller worked on the storyboards.

Praising the film's plot, voice acting performances and direction, Poortvilet said that he "couldn't stop laughing" and encouraged all fans of the show to see it.

[14] Writing for Animated Times, Azhan Ali ranked it at number three on a list of "Most Emotional Endings of Cartoons", and added that the final scene was "heartwarming because the Eds are no longer social outcasts".

[15] Collider reviewer Austin Allison named the film as the fourth best among a list of "Top 11 TV Cartoon Movies", deeming it a "surprisingly cathartic" creation that "finally gives the Eds a sense of belonging and acceptance that is more valuable to them than all the jawbreakers in the world.

He declared it a "perfect" end for the series because of the "finality" and the way Ed, Edd n Eddy's "longest-running gags, mysteries, and character relationships" were finished.

Carter also called this "the perfect homage to a show about imperfect people" and stated it featured "deep and profound personal experiences that lead to significant growth".

[18] When noting how Big Picture Show and the series' three holiday specials were excluded from HBO Max in June 2021, Comic Book Resources contributor Noah Dominguez called the movie's absence "probably the most glaring omission" among the Ed, Edd n Eddy episodes featured for how it was the "true series finale, sending the Eds on an epic journey and completing their character arcs in order to end the show on a high note".
