On Site with Thomas

Jack and the Pack is a direct-to-video release of the series Thomas and Friends. The thirteen episodes feature the Sodor Construction Company, or The Pack: a group of characters introduced in Season 6 with the intent to launch a spin-off series.

In the US, the episodes were featured on three DVDs: "On Site with Thomas" in 2006, "Thomas' Trusty Friends" in 2007, and "Mud, Glorious Mud" in 2008. In the UK (released October 2006) and Australia (October 2007), they were released in the form of a single DVD of 11 episodes ("Thomas' Trusty Friends"). The two excluded episodes, "Jack Owns Up" and "Percy's Scary Tale" had a limited release on single DVDs available initially at Woolworths and later The Sunday Mirror.

The episodes were narrated by Michael Angelis in the United Kingdom and Australia and by Michael Brandon in the United States. The musical scores for each episode were composed by Robert Hartshorne. The DVD with 11 episodes was also released in The Netherlands in 2009 narrated by Erik de Zwart.

Though the episodes were released in 2006-2008, the filming was in the original 35mm camera format, and the original four-and-a-half-minute running length (as opposed to the digital photography and seven-minute running length that have been in use since 2004).
