Transformers One, the first animated Transformers movie in decades, should debut around $30 million. Previews begin tonight.

The voiceover cast includes Chris Hemsworth, Brian Tyree Henry, Scarlett Johansson, Steve Buscemi and Keegan-Michael Key. Transformers One is the origin story of the once friendly relationship between Optimus Prime and Megatron.

Halle Berry stars in the R-rated horror flick Never Let Go that might exceed $5 million this weekend.

Another horror film, The Substance, stars Margaret Qualley and Demi Moore. A medical procedure goes awry when an aging fitness instructor takes The Substance to become a young and popular influencer. Revenue will be lucky to crack $3 million. (Deadline)
