Editors originally wanted the boxes showing separate characters to overlap but Stephen Hopkins decided not to do this. The writers were intentionally secretive about whether Teri Bauer would be killed in the final episode. To cast doubt about the outcome, three endings were filmed, two of which showed that Teri survived. Writers Joel Surnow and Robert Cochran originally planned for Teri to survive, but half-way through the season, they decided that a happy ending would not be as satisfying. They instead went with the ending where Teri dies. Surnow explained, "It made the show feel more real. And it gives our audience a sense when they're going to watch the show next season, of not being able to expect anything they’ve come to expect in a normal television show." Trailer The trailer for the first season aired some time between April and November, 2001. The trailer announces that David Palmer may become the first black U.S. President and shows Jack Bauer learning about the assassination attempt and corruption within his agency. Notably, the trailer shows the explosion of a commercial plane that was edited out of the show in response to the September 11 attacks. All other scenes shown are from the premiere episode. Reception The first season received universal acclaim, scoring a Metacritic rating of 88/100 based on 27 reviews. On Rotten Tomatoes, the season has an approval rating of 95% with an average score of 8.7 out of 10 based on 21 reviews. The website's critical consensus reads, "Brimming with tension and political intrigue, 24 successfully introduces its unique, high-concept format and a compelling hero worth watching in Kiefer Sutherland's Jack Bauer." Kiefer Sutherland won the Golden Globe Award for Best Actor – Television Series Drama and the Satellite
