The classic 1960 film starred Rod Taylor and was directed by George Pal. More recently, Simon Wells, great grandson of H.G., directed a re-make with Guy Pearce and Samantha Mumba. This was disappointing in some ways but introduced a version of the time travel paradox - the traveller is only driven to complete his invention following the death of his girlfriend, and tries repeatedly to save her life - each time, she is killed in some other, quite different but equally unexpected way. Eventually he stops trying and instead sets off for the future, where he is finally given a sad explanation for the paradox.
There's also an official, Wells-estate-sanctioned sequel written by Stephen Baxter, The Time Ships. In this book time travel has consequences: the traveller has returned from the future and shared his experiences and this has changed the future. Baxter's story uses the time travel device to explore a range of imaginative scenarios including a First World War that has persisted for decades, and a future where the Morlocks developed very differently from Wells' description - all the while developing Wells' ideas about class and evolution.
