Question: Megalyn Echikunwoke played a comic book character in what movie?
Context: Sheena, Queen of the Jungle is a fictional American comic book jungle girl heroine, originally published primarily by Fiction House.  She was the first female comic book character with her own title, with her 1937 (in Great Britain; 1938 in the United States) premiere preceding "Wonder Woman" #1 (cover-dated Dec. 1941).  Sheena inspired a wealth of similar comic book jungle queens.  She was predated in literature by Rima, the Jungle Girl, introduced in the 1904 William Henry Hudson novel "Green Mansions".  Sheena was ranked 59th in "Comics Buyer's Guide"s "100 Sexiest Women in Comics" list. Nero is a Flemish comic book character and the main protagonist in Marc Sleen's long running comic book strip series "The Adventures of Nero" (1947–2002).  He is one of the most recognizable comic book characters in Belgium and comparable to Lambik from the "Suske en Wiske" series by Willy Vandersteen. Vixen (Mari Jiwe McCabe) is a comic book character created by Gerry Conway and Bob Oksner.  She first appeared in "Action Comics" #521 (July 1981), published by DC Comics. Megalyn Echikunwoke ( ; born May 28, 1983) is an American actress.  She is perhaps best known for her roles as Tara Price in "", Isabelle Tyler in "The 4400" and Mari McCabe/Vixen in the Arrowverse. Barok is considered as one of the most popular komiks characters in the Philippines created by Filipino cartoonist Bert Sarile and Filipino comic book script writer Polly Rallanca in 1973.  A stone-age Philippine comic book character, Barok was described by Sarile as a lead character and one of the equivalents in the Philippine comic book industry of the American cartoon characters in The Flintstones.  Barok was illustrated in komiks by Sarile as a “pre-historic caveman” who carried a “large club”. In the comic book fan community, the apparent death and subsequent return of a long-running character is often called a comic book death.  While death is a serious subject, a comic book death is generally not taken seriously in the real world and is rarely permanent or meaningful other than for story or thematic purposes.  Commenting on the impact and role of comic book character deaths, writer Geoff Johns said: Dream is a fictional character appearing in American comic books published by DC Comics' imprint Vertigo.  The character is the protagonist of the comic book series "The Sandman", written by Neil Gaiman.  One of the seven Endless, inconceivably powerful beings older and greater than gods, Dream is both lord and personification of all dreams and stories, all that is not in reality (which, in turn, Dream may define by his existence).  He has taken many names, including Morpheus and Oneiros, and his appearance can change depending on the person who is seeing him.  Dream was named the sixth-greatest comic book character by "Empire Magazine".  He was also named fifteenth in IGN's 100 Top Comic Book Heroes list. Painkiller Jane is a television film based on the comic book character of the same name.  It was first broadcast on the Sci-Fi Channel on December 10, 2005.  The 2-hour film stars Emmanuelle Vaugier as the titular heroine.  The film differs significantly from the story of the comic book character. The Arrowverse is a shared fictional universe that is centered on television series airing on The CW, developed by Greg Berlanti, Marc Guggenheim, Andrew Kreisberg, Phil Klemmer, and Geoff Johns, based on characters appearing in publications by DC Comics.  The shared universe, much like the DC Universe in comic books or the cinematic DC Extended Universe, was established by crossing over common plot elements, settings, cast, and characters.  The Arrowverse stars Stephen Amell as Oliver Queen / Green Arrow, Grant Gustin as Barry Allen / Flash, Megalyn Echikunwoke as Mari Jiwe McCabe / Vixen, with an ensemble cast leading "Legends of Tomorrow", including Arthur Darvill as Rip Hunter, Caity Lotz as Sara Lance / White Canary, Brandon Routh as Ray Palmer / Atom, Dominic Purcell as Mick Rory / Heat Wave, with Victor Garber and Franz Drameh as Martin Stein & Jefferson "Jax" Jackson / Firestorm.  Russell Tovey stars as Ray Terrill / The Ray. Marley Davidson (sometimes referred to as "Marley Davidson: Bronx Exorcist") is a fictional comic book character created by writer and comic book artist Sandy Jimenez.  It made its first appearance on June 15, 1995 in the self-titled independent comic book "Marley Davidson", which chronicled the exploits of a Jamaican ex-priest, operating as an exorcist and monster hunter in New York City.
