The War With Grandpa is a feel good, laugh out loud comedy that is something the entire family will enjoy. But it isn’t just hilarious, there are some extremely heartwarming moments too. This movie made me miss my grandfathers – like a lot. Seeing the connection that Peter and Grandpa Ed have, despite being at war with one another, truly touched my heart. 

In The War With Grandpa, Grandpa Ed is forced to move in with his daughter Sally’s family. He isn’t happy about it but someone else is even more upset — his grandson Peter. You see, Ed ends up taking Peter’s bedroom, and Peter is forced to move to the attic. He decides he wants his room back and sends his grandfather a literal declaration of war. What follows is a whole lot of hilarious pranks, and perhaps not surprisingly, some strong bonding between the two.

A Hilarious Prank War

This whole movie is based on a prank war between Grandpa Ed and Peter. The lengths that they go to just to get to one another is absolutely hilarious. Some of the things that happen to them, I felt, deep in my soul. I don’t want to say too much but one “prank” involves a video game and I wanted to cry for Peter, being a big gamer myself. 

One of my favorite parts of this movie is that before they go too far, they draft up the rules of engagement. Things like no civilians (the rest of the family) being hurt in the process. That scene made me chuckle because I could totally see my husband being this serious about a prank war with one of our nephews, daughters, or other family members.

Young Vs. Old

The epic prank war between Grandpa Ed and Peter gets more and more involved as the movie goes on.  But it isn’t just the two of them in on it, they each have a group of friends who help them out. This gives part of the movie and young versus old feel. The younger and limber versus the older and more experienced. 

Cheech, Christopher Walken, and Robert De Niro make a great trio, and with the addition of Jane Seymour, I was laughing until my sides hurt. They make the perfect team to be going up against a group of young kids.  There is a dodgeball game scene that is EVERYTHING! I don’t want to give anything away but keep an eye out for that part and make sure you aren’t taking a drink during it, because you just might spit it out everywhere!

How Is The Child Acting Though?

Let’s be honest, child actors are not usually the best. I don’t mean they are bad, but they tend to overact. There are a fair amount of child actors in this movie, with Oakley Fegley being at the forefront. Each and every one of them brings something to the table in this movie. I was actually kind of shocked that not one of the kid actors bothered me in the slightest.

The youngest of the group, Poppy Gagnon, was actually the standout for me. She plays Peter’s younger sister Jennifer and has a strange obsession with Christmas. Not only is she always asking to play Christmas games, or watch Christmas movies, she is only seen in Christmas clothes. She even has a Christmas themed birthday party – in September. Nearly every scene she is in had me cracking up. Poppy is a talented young actress that I am sure we will see a lot more of.

Overall Thoughts

The War With Grandpa brings all the laughs! Trust me on that one. It is great for families but be warned, it might inspire your children to start a prank war. Keep the glue and hot sauce away from them. In all honesty though, it teaches a lot about the importance of family, being kind to one another, and why you should never start a war in the first place. No matter what kind of war it is – there will always be unforeseen consequences. 

I was excited to learn that this movie is actually based on a book, and I have since ordered it for my daughters, because I know they will enjoy reading it! Get ready to laugh until your cheeks hurt with The War With Grandpa, a feel good family film that is perfect for movie night!

Oh, and it ends with a hint that there just might be another war on the horizon — and I have my fingers crossed for a sequel!

About The War With Grandpa

Sixth-grader Peter (Oakes Fegley) is pretty much your average kid. He loves gaming, hanging out with his friends and his beloved pair of Air Jordans. But when his recently widowed grandfather Ed (Robert De Niro) moves in with Peter’s family, the boy is forced to give up his most prized possession of all, his bedroom.

Unwilling to let such an injustice stand, Peter, with the help of his closest buddies, devises a series of increasingly elaborate pranks to drive out the interloper. But Grandpa Ed won’t go without a fight. He even enlists his own pals – Jerry (Christopher Walken), Danny (Cheech Marin) and Diane (Jane Seymour) – to join the battle. Soon, it’s all-out war, with each side willing to stop at (almost) nothing to claim victory.

As tensions mount, Peter’s family – dad Arthur (Rob Riggle), mom Sally (Uma Thurman) and sisters Mia (Laura Marano) and Jennifer (Poppy Gagnon) – remain blissfully unaware of the goings-on under their own roof. That is, until everything comes to a head during one unforgettable backyard birthday party.

Based on the best-selling novel by Robert Kimmel Smith, THE WAR WITH GRANDPA features an all-star cast led by Robert De Niro and Oakes Fegley as Peter, also featuring Christopher Walken, Cheech Marin, Jane Seymour, Rob Riggle and Uma Thurman. Directed by Tom Hill (Hop, Alvin and the Chipmunks) from a screenplay by Tom J. Astle and Matt Ember (Get Smart), THE WAR WITH GRANDPA is produced by Marvin Peart, Rosa Peart and executive produced by Tre Peart.

The War With Grandpa hits theaters October 9th.
