Monte Walsh (2003 film): Monte Walsh is a 2003 Western television film directed by Simon Wincer and starring Tom Selleck, Isabella Rosellini, and Keith Carradine.  Loosely based on the 1963 Western novel "Monte Walsh" by Jack Schaefer, the film is about two long-time cowboys whose solitary and predictable lives on the range are inexorably changed when a fellow cowhand becomes involved with rustling and killing.  Set in Wyoming and filmed in Alberta, Canada, "Monte Walsh" is a remake of the 1970 theatrical film "Monte Walsh", starring Lee Marvin.  The script is nearly word-for-word identical to the original (original screenwriters David Zelag Goodman and Lukas Heller are credited) and a lot of set-ups and shots are the same as well, but Selleck plays a much more amiable and kind Walsh, to the point that some of the harsher lines attributed to Marvin's Walsh are given to other characters to soften the title character's personality to match Selleck's more affable style.  In 2003, "Monte Walsh" received an Emmy Award nomination for Outstanding Sound Editing for a Miniseries, Movie or a Special, and in 2004, the film received the Western Heritage Awards Bronze Wrangler for Outstanding Television Feature Film.
