The Many Adventures of Winnie the Pooh ends with a conversation about doing nothing and staying friends forever. Now watch the beginning of Pooh's Grand Adventure: The Search for Christopher Robin. It's the same conversation, word for word, making the latter movie the direct sequel of the former. - Kintatsu
- One teaser trailer did say that this took place where Many Adventures left off.
- It also gets another callback at the very end of the movie, which also recreates the last sentences of the book and ends with:
And here we shall leave them. And here we shall find them again. For the boy and the bear will always be together in this remarkable place ... called the Hundred Acre Wood.
