Question: what is a movement an actor in A Flag is Born involved with for years? 
Context: Sunil "Neil" Tagare (born c. 1962) is an entrepreneur.  He developed the concept of the Fiber-Optic Link Around the Globe (FLAG) project in 1989 when he was 27 years old.  FLAG was the first privately financed submarine fiber optic cable to link several continents around the world.  The cost of construction of the first phase was $1.5 billion.  As the executive vice president of Marketing and Business Development at NYNEX (now Verizon), Tagare was responsible for breaking through regulatory barriers in some of the most difficult countries in the world such as Spain, Italy, Egypt, India, Saudi Arabia, China, Hong Kong, Korea and Japan.  FLAG was featured in the Guinness Book of World Records as the longest telephone cable in the world and has been instrumental in lowering the cost of international calls to countries like India by an order of magnitude that facilitated the creation of new industries like offshore call centers. Surendranath Tagore (1872–1940) was a Bengali author, literary scholar, and translator.  He is particularly noted for translating a number of works of Rabindranath Tagore to English.  A member of the Tagore family of Calcutta, he was born to Satyendranath Tagore and Gyanodanandini Devi in Bombay in 1872.  Surendranath's sister Indira Devi Choudhurani, born in 1873, was a noted littereaur, author and musician.  He graduated from St Xavier's college, Calcutta in 1893, and at an early stage in his life he became involved in the Indian nationalist movement.  He was involved in supporting strike by railway workers in Bombay in 1899, and subsequently became involved in the "Swadeshi" movement in Bengal, in opposition to the 1905 partition of Bengal.  Surendranath is also believed to have been involved in the early phase of revolutionary movement for Indian independence, when he served as the treasurer of the "Anushilan Samiti" established under Pramatha Mitra.  Surendranath is credited with establishing a number of Indian-owned banks and insurance companies through which he sought to encourage indigenous industries.

At the age of 12, he was recruited for the Moroccan running team and sent to Rabat to train.  For ten years he participated in international races under the Moroccan flag.  By 1999 he was the triple cross-country champion for Morocco, had won 2nd place in the Africa Championships and was two-time Arab World Champion.  In 2004 during a race in France where he participated under the Moroccan flag, he raised the Saharawi flag above his head during the last few hundred metres of the race.

A Movement director is involved with actor movement in a variety of production settings that include theatre, television, film, opera and animation.  Movement directors usually work closely with the director and the performers, collaborating with the creative team to realise the physical life of a work.

The movement director may create, or research and pass on, embodied information about etiquette, ethnicities (including proxemics, gestural language, social codes, etc.), a character’s condition (related to medical conditions within their historical context, and factors such as inebriation, pregnancy, etc.) and personal journey (ageing, etc.), as well as specialist movement (e.g. period dances, dexterity in falling, lifts and acrobatics, animal work, cross-gendered performance) or chorus work.
