Watch Longitude

Longitude is a historical drama miniseries that first aired on ITV in 2000. The series is an adaptation of the book "Longitude: The True Story of a Lone Genius Who Solved the Greatest Scientific Problem of His Time" by Dava Sobel. The show is set in the 18th century and follows the life and work of John Harrison (played by Jeremy Irons), a clockmaker who invented the marine chronometer, an instrument that helped sailors determine their longitude at sea.

The show is divided into four parts, with each episode spanning approximately 50 minutes. The first episode introduces John Harrison and his struggle to get his marine chronometer recognized as a viable solution to the longitude problem. Harrison faces opposition from the scientific community, who believe the problem can only be solved by observing the stars. Meanwhile, the government offers a prize of £20,000 to anyone who can solve the longitude problem, but the criteria for winning are vague and constantly changing.

The second episode focuses on Harrison's early life and his first attempts at building a marine chronometer. He faces numerous setbacks due to insufficient funding and lack of support from his family. He finally gains recognition and funding from clockmaker George Graham (played by Nigel Davenport), who recognizes the potential of Harrison's invention.

In the third episode, Harrison faces his greatest challenge yet as he tries to overcome technical difficulties and prove the accuracy of his marine chronometer. He sails to Jamaica with his son (played by Liam Jennings) to demonstrate the instrument's capabilities to the Deputy Governor (played by Michael Gambon). However, Harrison's efforts are beset by challenges, from inclement weather to sabotage by those who want to prevent him from winning the longitude prize.

The final episode of the series follows the aftermath of Harrison's successful demonstration of his marine chronometer. Although he proves that his instrument is accurate and reliable, the scientific community remains skeptical of his methods. Harrison struggles to secure recognition for his work and win the longitude prize, while also dealing with personal troubles, including the declining health of his wife (played by Gemma Jones).

The cast of Longitude is led by veteran actor Jeremy Irons, who gives a nuanced and captivating performance as John Harrison. The supporting cast is also excellent, with standout performances from Michael Gambon as the skeptical Deputy Governor of Jamaica and Anna Chancellor as Harrison's tenacious daughter. Stephen Fry and Samuel West also make brief appearances as members of the Royal Society.

One of the strengths of Longitude is its attention to historical detail. The series recreates the 18th century setting with remarkable accuracy, from the costumes and sets to the language and mannerisms of the characters. The show also highlights the social and political context of Harrison's work, including the role of the British Empire and the scientific establishment in shaping the longitude prize.

Overall, Longitude is a compelling and engaging drama that brings to life the story of one of the greatest scientific achievements of the 18th century. The show combines excellent performances, a fascinating historical setting, and a gripping storyline to create a memorable viewing experience for audiences.

Longitude is a series that ran for 1 seasons (2 episodes) between December 30, 2000 and on ITV
