His portrayal marked the revival of the beloved series after a long hiatus, and he quickly became a fan favourite. Eccleston's season, which consists of 13 episodes, introduced a new generation to the Doctor's adventures, alongside his companion, Rose Tyler, played by Billie Piper.
Eccleston's tenure as the Doctor was notable for its darker tone and emotional depth, exploring themes of loss and redemption. His first episode, Rose, aired on 26 March 2005, and he continued to captivate audiences until his departure in the finale, The Parting of the Ways, where he famously regenerates into David Tennant's Tenth Doctor. This episode aired on 18 June 2005, marking the end of Eccleston's time in the TARDIS.
Despite his success, Eccleston's departure from the show was shrouded in controversy. He left after just one season, citing creative differences and a desire to avoid being typecast. This decision left many fans disappointed, as they had hoped to see more of his interpretation of the iconic character.

In recent years, there has been speculation about Eccleston's return to the series. He has expressed a willingness to reprise his role, and fans are eager to see him reunite with Billie Piper. While there have been no official announcements regarding a return, the possibility remains a topic of discussion among the Doctor Who community.
For those looking to revisit Eccleston's era, the entire season is available to watch on various streaming platforms, including BBC iPlayer and HBO Max. His portrayal of the Ninth Doctor continues to resonate with fans, and his episodes remain a significant part of Doctor Who history.
