 Question: can you crossbreed a wolf with a dog Context: At the time of The Golden Compass's theatrical release, Chris Weitz pledged to ``protect (the) integrity'' of the prospective sequels by being ``much less compromising'' in the book-to-film adaptation process. New Line Cinema commissioned Hossein Amini to write a screenplay based on the second book in the trilogy, The Subtle Knife, potentially for release in 2010 or 2011, with the third book of the trilogy, The Amber Spyglass, to follow. However, New Line president Toby Emmerich stressed that production of the second and third films was dependent on the financial success of The Golden Compass. When The Golden Compass did not meet expectations at the United States box office, the likelihood of a sequel was downplayed by New Line. According to studio co-head Michael Lynne, ``The jury is still very much out on the movie, and while it's performed very strongly overseas we'll look at it early 2008 and see where we're going with a sequel.''
 Question: did they ever make a golden compass 2 Context: Canadian law requires that all persons entering Canada must carry proof of both citizenship and identity. A valid U.S. passport or passport card is preferred, although a birth certificate, naturalization certificate, citizenship certificate, or another document proving U.S. nationality, together with a government-issued photo ID (such as a driver's license) are acceptable to establish identity and nationality. However, the documents required to return to the United States can be more restrictive (for example, a birth certificate and photo ID are insufficient) -- see the section below on Return entry into the U.S.
 Question: can you enter canada with a us driver's license Context: Four drivers (John Andretti, Robby Gordon, Tony Stewart and Kurt Busch) have attempted the Indianapolis/Charlotte ``Double Duty'' feat. Of these, Tony Stewart's 2001 effort stands as the best combined result. He finished 6th at Indianapolis and 3rd at Charlotte, completing all 1,100 miles. Among the handful of drivers in the 1960s and 1970s that attempted ``crossovers,'' Donnie Allison competed in both events in a year in which they were held on successive days.
 Question: has a nascar driver ever won the indy 500 Context: Running is a method of terrestrial locomotion allowing humans and other animals to move rapidly on foot. Running is a type of gait characterized by an aerial phase in which all feet are above the ground (though there are exceptions). This is in contrast to walking, where one foot is always in contact with the ground, the legs are kept mostly straight and the center of gravity vaults over the stance leg or legs in an inverted pendulum fashion. A characteristic feature of a running body from the viewpoint of spring-mass mechanics is that changes in kinetic and potential energy within a stride occur simultaneously, with energy storage accomplished by springy tendons and passive muscle elasticity. The term running can refer to any of a variety of speeds ranging from jogging to sprinting.
