The 17 Again actor gave his Instagram followers a look at his covert mission in which he broke his grandfather out of a retirement home. Though it's seemingly easy to check grandpa out for the day, Zac and brother Dylan upped the ante by stealthily walking through the lobby and hallways before stealing an employee badge—all while the Mission: Impossible theme music played in the background.
Having evaded capture, the brothers slipped into their grandfather's room, where their relative sat ready with a newsboy cap on. "Let's get out of here," the older gentleman quipped.
After wheeling grandpa out of the retirement home, the brothers went for a drive and got him a fresh Coca Cola along the way. They then went to their family home where they enjoyed the final game of the Euro cup.
In other words, the mission was a success.
When all was said and done, the brothers took their gramps back to the senior living center and Zac shared the lesson he learned from the experience: "My grandpa is better at acting than I am."
Naturally, the video drew praise for its creativity, while people complimented Zac's dedication. And even Charlie's Angels director Elizabeth Banks admired grandpa's acting skills, writing, "I love this so much."
According to Dylan, this was all done in the name of the game they love so much. Zac's younger brother commented on the video, "Just wanted to watch the Euro Cup with the boys."
