In a tweet sent out by The Walking Dead, the Coronavirus has impacted the season ten finale meaning that it cannot be finished in time to air.
(1/2) Current events have unfortunately made it impossible to complete post-production of The Walking Dead Season 10 finale, so the current season will end with its 15th episode on April 5. The planned finale will appear as a special episode later in the year. pic.twitter.com/DDkVd63ThU— The Walking Dead on AMC (@WalkingDead_AMC) March 24, 2020
Post production tends to involve visual effects, music and mixing and can tend to go on up to three weeks before the episode is due to air.
This is very disappointing news, especially since this season has been so enjoyable with episode after episode of incredible content. The finale was sure to be fantastic. But with our own virus to defeat, we will have to wait.
