The screenwriters of the film Grapes found inspiration with a real-life fraud Lukáš Kohout who travelled the whole world as a fake assistant to a member of parliament. Honza and Jirka send their grandfather to enjoy South America and they themselves head out to Moravia.

In the film, they both sit on the staircase, their backs to the building. The building in question is also not the parliament; it's the Ministry of Health. The area in front of Zítkovy Gardens is much more interesting. When the weather is in favour, the Rašín River Bank becomes swarming with people and cultural events.
