The document discusses signs, semiotics, and codes in film. It explains that codes are conventions that put signs together to create meaning. Films use syntograms, which are ordered series of signs that convey meaning. Signs have denotation, or dictionary definitions, and connotation, or implied cultural meanings. The relationship between a signifier and its signified is explained using the example of the word "tree." The document notes that genres like action films have expected conventions, and completing the assigned work would involve identifying these conventions.
