I Declare War is a 2012 Canadian action comedy-drama film written and directed by Jason Lapeyre and co-directed by Robert Wilson.

A neighborhood group of preteen friends play a game of capture the flag one Saturday afternoon in the local woods.

[3] The script was picked up by producer Lewin Webb of Samaritan Entertainment and he forwarded it to his partner Robert Wilson, where it went through years of development and financial issues.

"[13] Rick Groen of The Globe and Mail gave it 3 out of 4 stars, finding criticism in its meandering narrative, repetitious conceit and loose editing but found praise in the film "being buoyed by the naturalism of its exclusively young cast" and "effectively gets into your head and under your skin".

[14] Annlee Ellingson of the Los Angeles Times gave it 3 out of 5 stars, praising it for its charm and ending with "The performances may be slightly uneven across the cast of a dozen distinct personalities (plus a dog), but overall the effect works because, after all, they're just playacting … right?".
