Question: Sun Yu and Neil Marshall are both what?
Context: Little Toys () is a 1933 silent film directed by filmmaker Sun Yu.  It is one of two films Sun Yu directed in 1933 (the other being "Daybreak").  The film stars popular Chinese actress Ruan Lingyu and was produced by the leftist film production company Lianhua Film Company. Crossroads is a 1937 Chinese seriocomedy film directed by Shen Xiling, starring Bai Yang and Zhao Dan.  The film exemplified the growing trend of Chinese films by the mid-1930s of incorporating references (both veiled and explicit) to the war with Japan.  In this way, "Crossroads" joins films like "Blood on Wolf Mountain" by Fei Mu and "The Big Road" by Sun Yu. Sun Yu (March 21, 1900 – July 11, 1990) was a major leftist film director active in the 1930s in Shanghai.  One of the core directors of the Lianhua Film Company, Sun Yu made a name for himself with a series of socially conscious dramas in the early to mid-1930s.  After the Japanese invasion of China in 1937, Sun Yu made his way to the interior, where he continued to make films glorifying the war effort against the Japanese. Yu Xiusong () (1899 – February 21, 1939) was an early member of the Communist Party of China.  He was born in Zhuji, Zhejiang.  He started attending the Zhejiang First Normal School (currently Hangzhou High School) in 1916.  The May 4 movement of 1919 led him to be a student activist.  In 1920, he founded the Communist Youth League of China and became its first leader.  In 1922, he supported the Constitutional Protection Movement of Sun Yat-sen.  As a result of the First United Front in 1924, Yu was given a position in his home province by the Kuomintang.  In October 1925, Yu went to the Soviet Union to study at Moscow Sun Yat-sen University, where he became acquainted with Wang Ming.  In 1933, he was in the Soviet Far East.  He arrived in Xinjiang in the summer of 1935.  He was married to the sister of local warlord Sheng Shicai.  At the instigation of Kang Sheng, Wang had Deng Fa arrest Yu on charges of Trotskyism sometime between December 10 and 27, 1937.  In May or June 1938, Yu was extradited back to the Soviet Union.  He was sentenced to death and executed in Moscow.  Yu's death marked the final break between Wang and Zhang Guotao.  In 1962, after the Sino-Soviet split, Yu was posthumously proclaimed a revolutionary martyr. Zhou Yu (175–210), courtesy name Gongjin, was a military general and strategist serving under the warlord Sun Ce in the late Eastern Han dynasty.  He continued serving under Sun Quan, Sun Ce's younger brother and successor, after Sun Ce died in 200 CE.  Around late 208, the northern warlord Cao Cao led his forces south with the intention of conquering the Jiangdong region, where Sun Quan's territories were based.  Zhou Yu, as the frontline commander of Sun Quan's forces, defeated Cao Cao at the decisive Battle of Red Cliffs.  He then led Sun Quan's forces at the follow-up Battle of Jiangling and defeated Cao Cao's forces again.  Zhou Yu's victories helped to solidify the survivability of Sun Quan's regime, which served as the foundation of the state of Eastern Wu in the Three Kingdoms period (220–280).  He died in 210 at a relatively young age of 35 while preparing for a conquest of the Bashu region (covering present-day Sichuan and Chongqing). Sun Yu (177–215), courtesy name Zhongyi, was a cousin of Sun Quan, a warlord who lived in the late Eastern Han dynasty and later became the founding emperor of the state of Eastern Wu in the Three Kingdoms period.  Sun Yu was the second son of Sun Jing, a younger brother of Sun Quan's father Sun Jian. Lu Su (172–217), courtesy name Zijing, was a diplomat, military general and official serving under the warlord Sun Quan in the late Eastern Han dynasty.  In 200 CE, when Sun Quan had just taken over the reins of power, his adviser Zhou Yu recommended Lu Su as a talent to him.  Lu Su started his service under Sun Quan since then.  As one of Sun Quan's most important advisers in the warlord's early career, Lu Su is best known for making the following contributions.  Firstly, in 200 CE, he drafted a long-term strategy for Sun Quan's power bloc to emerge as one of three major contending powers in China – a plan similar to Zhuge Liang's Longzhong Plan, which was proposed about seven years later.  Secondly, before the Battle of Red Cliffs in late 208, he was the first person to persuade Sun Quan to ally with Liu Bei against Cao Cao.  Thirdly, he succeeded Zhou Yu as the frontline commander of Sun Quan's forces in 210 after Zhou's death and maintained the Sun–Liu alliance.  Fourthly, in 215, he represented Sun Quan at the negotiations with Liu Bei's general Guan Yu during the Sun–Liu territorial dispute over Jing Province. Yu Jin (died 221), courtesy name Wenze, was a military general serving under the warlord Cao Cao in the late Eastern Han dynasty.  He joined Cao Cao in 192 around the start of the civil wars leading to the collapse of the dynasty, and fought in many of the campaigns which established the warlord's position as a central figure in that period.  In 219, Yu Jin was tasked with leading forces to relief Cao Cao's general Cao Ren, who was being besieged in Fancheng by Liu Bei's general Guan Yu, but his armies were destroyed in a flood due to heavy rains.  Yu Jin surrendered to Guan Yu and became a prisoner-of-war, but was transferred to the custody of another warlord, Sun Quan, after Sun's forces captured Guan Yu's bases in late 219.  Sun Quan treated Yu Jin like a guest and sent him back to the state of Cao Wei – founded in late 220 by Cao Cao's successor, Cao Pi, who ended the Eastern Han dynasty – in 221.  Cao Pi pardoned Yu Jin and restored him to the position of a general.  However, Yu Jin died later that year in regret after visiting Cao Cao's tomb, where he saw illustrations of the Battle of Fancheng depicting his surrender to Guan Yu. Neil Marshall (born 25 May 1970) is an English film director, editor and screenwriter.  Marshall began his career in editing and in 2002 directed his first feature film "Dog Soldiers", a horror-comedy film which became a cult film.  He followed up with the critically acclaimed horror film "The Descent" in 2005.  Marshall also directed "Doomsday" in 2008, and wrote and directed "Centurion" in 2010.

The Big Road (), also known as The Highway, is a 1934 Chinese film directed by Sun Yu and starring Jin Yan and Li Lili.  It is a silent film but with music and sound effects added post-production.  The film deals with a group of workers who are constructing a highway for use in the war against the Japanese.
