Question: What two stars shared the screen with Andrew Keegan in the 2001 adaptation of William Shakespeare's "Othello"?

Context paragraphs:
Othello: Othello ("The Tragedy of Othello, the Moor of Venice)" is a tragedy by William Shakespeare, believed to have been written in 1603.  It is based on the story "Un Capitano Moro" ("A Moorish Captain") by Cinthio, a disciple of Boccaccio, first published in 1565.  The story revolves around its two central characters: Othello, a Moorish general in the Venetian army and his unfaithful ensign, Iago.  Given its varied and enduring themes of racism, love, jealousy, betrayal, revenge and repentance, "Othello" is still often performed in professional and community theatre alike, and has been the source for numerous operatic, film, and literary adaptations.

Othello error: Othello error occurs when a suspicious observer discounts cues of truthfulness.  Essentially the Othello error occurs, Paul Ekman states, "when the lie catcher fails to consider that a truthful person who is under stress may appear to be lying" their non-verbal signals expressing their worry at the possibility of being disbelieved.  A lie-detector or polygraph may be deceived in the same way, by misinterpreting nervous signals from a truthful person.  The error is named after William Shakespeare's tragic play "Othello"; the dynamics between the two main characters, Othello and Desdemona are a particularly notable example of the error in practice.

Emilia (Othello): Emilia is a character in the tragedy "Othello" by William Shakespeare.  The character's origin is traced to the 1565 tale, "Un capitano Moro" from Giovanni Battista Giraldi Cinthio's "Gli Hecatommithi".  There, the character is described as young and virtuous, is referred to simply as the ensign's wife, and becomes Desdemona's companion in Cyprus.  In Shakespeare, she is named Emilia, is the wife of Othello's ensign, Iago, and is an attendant to Othello's wife, Desdemona.  While considered a minor character in the drama, she has been portrayed by several notable actresses on film, with Joyce Redman receiving an Academy Award nomination for her performance.

Andrew Keegan: Andrew Keegan (born January 29, 1979) is an American actor best known for his roles in television shows including "Party of Five" and "7th Heaven" and in films such as "10 Things I Hate about You", "The Broken Hearts Club" (2000) and "O" (2001).

Othello (2001 film): Othello is a 2001 British television film starring Eamonn Walker, Christopher Eccleston and Keeley Hawes.  It is an adaptation in modern English of William Shakespeare's play "Othello".  It was scripted by Andrew Davies and directed by Geoffrey Sax.

O (film): O is a 2001 American drama film, and a loose modern adaptation of William Shakespeare's "Othello", set in an American high school.  It stars Mekhi Phifer and Josh Hartnett.

A Midsummer Night's Rave: A Midsummer Night's Rave is a film adapted from Shakespeare's "A Midsummer Night's Dream" released in 2002.  The film stars Corey Pearson, Lauren German, Andrew Keegan, Chad Lindberg, and Sunny Mabrey; and was directed by Gil Cates Jr..  It is set at a rave rather than a forest, as in the original.  The film received little attention from professional movie critics, but is considered a success with teen audiences, and has been used as an exemplar for a category of movies (the "McShakespeare", an example of McDonaldization) in more academic publications.

RX J0806.3+1527: RX J0806.3+1527 or HM Cancri (sometimes shortened to "HM Cnc" or "J0806" after establishing identity) is an X-ray binary star system about 1600 ly away.  It comprises two dense white dwarfs orbiting each other once every 321.5 seconds (in this system the "year" duration is of only 5.4 minutes), at an estimated distance of only 80000 km apart (about 1/5 the distance between the Earth and the Moon).  The two stars orbit each other at speeds in excess of 400 km/s .  The stars are estimated to be about half as massive as the Sun.  Like typical white dwarfs, they are extremely dense, being composed of degenerate matter, and so have radii of order the radius of Earth.  Astronomers believe that the two stars will eventually merge, based on data from many X-ray satellites, such as Chandra X-Ray Observatory, XMM-Newton and the Swift Gamma-Ray Burst Mission.  These data show that the orbital period of the two stars is steadily decreasing at a rate of 1.2 milliseconds per year as they thus are getting closer by approximately 60 cm per day.  At this rate, they can be expected to merge in approximately 340,000 years.  With a revolution period of 5.4 minutes RX J0806 is the shortest orbital period binary system currently known.

Visual binary: A visual binary is a gravitationally bound system that can be resolved into two stars.  These stars are estimated, via Kepler's 3rd law, to have periods ranging from a number of years to thousands of years.  A visual binary consists of two stars, usually of a different brightness.  Because of this, the brighter star is called the primary and the fainter one is called the companion.  If the primary is too bright, relative to the companion, this can cause a glare making it difficult to resolve the two components.  However, it is possible to resolve the system if observations of the brighter star show it to wobble about a centre of mass.  In general, a visual binary can be resolved into two stars with a telescope if their centres are separated by a value greater than or equal to one arcsecond, but with modern professional telescopes, interferometry, or space-based equipment, stars can be resolved at closer distances.

Kill Speed: Kill Speed (also called Fast Glass) is a 2010 action film directed by Kim Bass, who is a commercial rated pilot.  It stars Andrew Keegan, Brandon Quinn, Nick Carter, Natalia Cigliuti and Greg Grunberg in an aviation-themed crime/thriller drama.  The film features music by: Steppenwolf, Tears for Fears, Nick Carter, Jada Pinkett-Smith’s Wicked Wisdom; and world-renowned bass guitarist Nathan East.
