- Grischka: "And this...for my brother!"
- James Bond: "And that's for 009."
- ―Grischka and James Bond[src]
Twin knife throwers Mischka and Grischka feature prominently in Octopussy's circus. Kamal Khan and General Orlov (Steven Berkoff) also secretly employ the pair as assassins. When Agent 009, disguised as a circus clown, steals a fake Fabergé egg from Octopussy's circus in East Berlin, Mischka and Grischka give chase. They eventually throw a knife into his back, fatally wounding him. 009's murder and the recovery of the fake Fabergé egg from his body bring James Bond to investigate.
In Karl Marx Stadt, Bond witnesses the knife throwing skills of the twins despite being told not to leave his seating with the Russians.
Later, on board Octopussy's train, Mischka uses a welding torch to attack Bond as he enters a car housing Khan's and Orlov's atomic bomb. Momentarily blinded, Bond pulls a lever just in time, bringing the circus' heavy cannon down on Mischka, instantly killing him. Bond then disguises himself in Mischka's clothes. When Grischka sees Khan's henchman Gobinda battling Bond, who is dressed in his brother's clothes, he realizes that his brother has been murdered. Bond and Grischka fight and fall off the train. Grischka pursues 007, pinning him to a cabin door with knives. Bond turns the tables on the vengeful twin by throwing one of Grischka's own knives into his stomach, avenging the murder of 009.
