Bully beef (or corned beef in the United Kingdom) refers to the variety made from finely minced corned beef in a small amount of gelatin (bully beef; from the French "bouilli" "boiled"), and is sold in distinctive, oblong cans, just as in the United States and Canada, or in slices from supermarkets.
 It is mainly imported from Argentina, Brazil, or Uruguay.
 Bully beef and hardtack biscuits were the main field rations of the British Army from the Boer War to World War II.
 It is commonly served sliced in a corned beef sandwich.

Bresaola (] ) is air-dried, salted beef (but also horse, venison and pork) that has been aged two or three months until it becomes hard and turns a dark red, almost purple colour.

Aleksandr Lukich Ptushko (Russian: Алекса́ндр Луки́ч Пту́шко , Ukrainian: Олександр Лукич Птушко ; 19 April [O.S. 6 April] 1900 in Lugansk, Russian Empire (now Luhansk, Ukraine) – 6 March 1973 in Moscow, Soviet Union) was a Soviet animation and fantasy film director, and Meritorious Artist of the RSFSR.
 Ptushko is frequently (and somewhat misleadingly) referred to as "the Soviet Walt Disney," due to his prominent early role in animation in the Soviet Union, though a more accurate comparison would be to Willis O'Brien or Ray Harryhausen.
 Some critics, such as Tim Lucas and Alan Upchurch, have also compared Ptushko to Italian filmmaker Mario Bava, who made fantasy and horror films with similarities to Ptushko's work and made similarly innovative use of color cinematography and special effects.
 He began his film career as a director and animator of stop-motion short films, and became a director of feature-length films combining live-action, stop-motion, creative special effects, and Russian mythology.
 Along the way he would be responsible for a number of firsts in Russian film history (including the first feature-length animated film, and the first film in color), and would make several extremely popular and internationally praised films full of visual flair and spectacle.
