The story is about a guy that enlist in the army and brings a friend - the frog "Krek". This is not liked by the sergeant, who does everything in his power to get rid of it...This is a brilliant short animated film that won the Silver Bear at Berlin Film Festival in 1967.Borivoj Dovnikovic "Bordo" started out as a cartoonist and illustrator for newspapers, and went 1950 on to make short animated films in the famous Zagreb School of Animated Film. He has made shorts as "The Flower Lovers" (1970) and "One day in life" (1982), which is my personal favorites (together with "Krek"). He is also responsible for "Balthasar - The Inventor of Shoes", which inspired to a whole TV-series with Balthasar in the seventies.Bordo has in "Krek" managed to catch the absurdities of militarism and the life in the army with graceful and direct slapstick humor. A must see for anyone who loves animation!!
