Daniel P. Hanley, A.C.E. (born 1955) is a film editor who won an Academy Award for the film Apollo 13 (1995). Hanley and his editing partner Mike Hill have had a notable collaboration with the director Ron Howard, having edited all of Howard's films since Night Shift (1982). In addition to Apollo 13, Hanley and Hill were nominated for Academy Awards for Howard's A Beautiful Mind (2001), Cinderella Man (2005), and Frost/Nixon (2008).
Hanley and Hill's longstanding partnership, which includes 18 films through the 2009 Angels and Demons, may be unique among major film editors. An important aspect of the partnership is that the two editors have developed a sufficiently uniform style that they can simply split up the scenes of each film without specialization.
