OK, here's one.
Jacky Chan and Will Smith (good guys) vs Jason Strefan and Jet Li, as time traveling cops going through history, each one changing the effects of the other. Such time traveling moments include...
- Martial arts coming from Africa and not china, china are human-rights herothinggys.
- Dinosaurs, not sure where yet, but they'll be there. Will Smith will look after a baby one.
- Jacky Chan and Jet Li having a single fight scene that jumps from time-zone to time-zone.
- Some sort of Knights of the round table moment.
- Will Smith dies in the past, and they go find his grave from the 15th century.
- In the future, everything is normal, until you realise half the people are robots.

It's important for any good timetravel plot
that halfway through the good guys and the bad guys swap places.

YES !
And they'll be a bit where Will Smith punches through a portal and his hand comes out white, then he pulls it back through and it's black again.
