That's just a weird contractual obligation thing due to them doing the remake. They're not really involved in production. Execuitve Producer credits are often just contractual formalities or emeritus style shout outs.

They've already said during media rounds the past few weeks don't expect any Jaden Smith or Jackie Chan because it isn't the same continuity.
