I haven't watched the movie, I am just copy-pasta-ring, to flesh out the conversation, so to add a cherry on top I asked your question to GPT, and this is what I got:

[AI] No, House of Dynamite is not a remake of The Sum of All Fears, but both films deal with similar themes of a nuclear crisis and the U.S. government's response to it. House of Dynamite is a separate and new film from Kathryn Bigelow, while The Sum of All Fears is an adaptation of a Tom Clancy novel. House of Dynamite (2025): This is a new, original film directed by Kathryn Bigelow about a nuclear missile launched by an unidentified enemy and the U.S. government's response. The Sum of All Fears: This is a film based on a Tom Clancy novel that also involves a nuclear attack scenario in the United States.
